On board of my ship, i am the captain

And i am in control. For that, i need levers, buttons and a steering wheel, period.

This is proto three, notice the different color of the steering column housing. The stalk is mounted solidly, problems like the horn and turn signal return cam are in the process of beeing fixed.

long time no see

Ok, it’s been a bit silent on this side of the pond.

But like a duck, calm on the topside – with busy feet underwater, i have been working on the project every single day. 14 hour shifts at best.

Last time i left you the old 225 had been removed. It has sold in the meantime and is running well in a Dart. Yay!

IMG_20160816_200444

I got frustrated with a few of the problems i encountered with the front suspension and shifted my attention to the wiring and electrical mess this project is.

IMG_20160903_161332

Well, at least it looks like most of it will just work.

I removed the ABS module, just to notice that this is the brake pedal switches gateway to the BCM and the brake lights… Some kind of solution has to be found to get around that.

At least the engine still wants to start without the ABS, i don’t yet know if it will enter limp-mode but i will deal with that when i get this far.

Step one was getting to know how much excess wire there is and where it is. Easier said: Layout the harness in the cab and cut it down until it fits.

For this task i made a “sketch” of the cabs floor and firewall on the shop floor, using tape and a sharpie.

Obviously there is lots of extra wire length calculated in this setup.

Without the cage i don’t know exactly where stuff will end up and this way i can still move the inside fuse box around for example.

Doing it this way made things SO much easier to begin with. Then came the work on the major details. Like situating the BCM. Easier done than said.

img_20160908_154227

I put it on a homegrown bracket, made from aluminum flat stock and with some rivets attached it to the heater box.

img_20160908_160451

Can’t be seen from the seated position, all connectors easily at reach and it’s mounted pretty solid.

With that module positioned, i was able to route the power cables and the signal wires. Intentionally i split the original loom into signal and power and routed these far from eachother on the floor. On the one hand, this allows for smaller wire bundles and on the other, if something fries the power wires, it does not fry the signal wires as well. At least that was the original thought.

At this point, i wanted to know where the start button could be located. Easy.

img_20160906_155450

I made a template, traced that out on the dashboard and a reinforcement plate, riveted that reinforcement plate into the dash and made a nice large hole in the plastic cover.

And then came the greatest success and easiest mod to the truck so far, as of mounting electrical stuff to it:

IMG_20160905_140404

IMG_20160905_140808

I drilled ONE hole and the accelerator pedal bolted just up. The other hole was in a perfect spot already. It felt a little light for my big and heavy feet, which is why i added an old throttle return spring to it. Now it feels nice and stiff.

IMG_20160905_141823

So easy, i still giggle about it.

Once i had developed the layout of the cab harness far enough to make the first pass-throughs i took a deep breath and shot two large holes into the cab (second one not pictured here). This is the branch of the PDC that sits in the engine bay, feeding power to the BCM. And some more sensor wires, wiper control, etc.

img_20160909_143412

The Challengers harness came with a lot of nice plastic pieces to route wires around corners. I am re-using everything i can. This is the bottom of the heater box for example.

img_20160909_163614

Behind the glove box (it still fits, no problem). The heater box received more holes, so i can mount connectors to it. The RF-hub (communication with the key fobs) sits here as well.

img_20160909_163429

A lot of this excess wiring has already been cut, soldered and wrapped for good. The outside connections for lighting, fuel pump, etc. have been made with AMP SuperSeal connectors. I had an assortment of these and used it for good.

img_20160923_203304

img_20160923_203154

You can see that stuff was dangling around on the passenger side of the engine compartment. A situation that called for immediate action and organization.

Flat stock aluminum, bending measures, rivets and rubber grommets are the only ingredients of this goodness:

img_20160924_175750

img_20160924_190139

Wonder what these heater hoses are on the heater box? Re-purposed Challenger stuff.

IMG_20160818_202634

During all of this, i made repeated tests to see wether everything still starts up.

img_20160916_202710

Don’t ask where the housing of the dash is, you won’t get an answer.

By the magic of resistors and reading the FSM, the old light switch now controls the new lighting functions. But i am still thinking about putting a new light switch in the vehicle. Not decided for good yet.

We are reaching the end and the most destructive phase of this blog post.

How do i get a modern turn signal stalk with high beam and wiper control on this steering column.

You’d say that’s easy, just buy a column from an early 90s truck. Unfortunately these columns are SO damn ugly and also scarce (because i need a manual transmission column!).

Which is why i gave in to one of my “it might fit”-moments and ruined three column housings as prototypes in the task of integrating the Challengers turn signal stalk into a Dodge truck steering column. Hacking at its best.

img_20160924_202310

img_20160924_202300

That’s the second proto. The stalk is still too far away from the steering wheel and got moved closer by 1/2″ and further outboard by 1/2″ on the third proto.

The third is actually looking pretty good. I am doing final stuff on this third proto, like installing the turn signal return cam, etc.

Destructive testing with a positive outcome, i hope.

Stay tuned.

In the next installment i will tear into the front suspension parts of the frame, get starting and find a fix for the tail lights (because these extra complicated by design) and i may hang the engine in the frame for the first time.

Money IS an object

Struck me a few minutes ago:
My 6.4 came without a power steering pump.
It looks like the donor car had EHPS or Electro Hydraulic Power Steering.
This is an electric pump providing the hydraulic pressure for a “regular” hydraulic assisted steering rack. Yay.
So instead of a pump my engine has an idler where the power steering pump would go on a similar engine:
6.4L HEMI turnkey 11
You can see it very clearly on the drivers side of the motor (right side in image) above the A/C-compressor.
I know how to fix this: Mopar RL181778AB 2011-2013 Challenger with 6.4L, just like 340 USD … used ones seem to be scarce and Rockauto already has the best price for a new OEM Mopar part.
I could sink several tenthousand dollars into this thing right away. I’ll try to avoid that…

Farewell

Farewell from the old venerable 225.

IMG_20160816_200444

For a few days until i drop in the 6.4.

It’s wiiiiiiiiiiide

OH YEAH BABY! Christmas times 5 was today!

IMG_20160812_183842
And then i thought, oh shoot, this axle is damn wide.

IMG_20160812_183907

I have a regular 8-lug D60 stealing space in my shop and i thought this thing was big.
This SRT-10 axle is even bigger. 3.5″ axle tubes really do look huge in person.

With the wheels i intend to use this axle is 1955.8 mm wide (outside of the wheel).

Act of desperation

As an act of desperation i will now try to modify the front suspension crossmember of a ’05 Ram to fit the D150s frame.

I am really getting nowhere trying to make other vehicles stock parts work with the original strut rod suspension.

For a small pricetag i will get myself a cut-off of a parted out ’05 Ram 1500, something like this:

s-l160046545

The plan is to liberate the crossmember from the frame rails and carefully adapt stuff to my trucks frame. Including boxing the mounting points where necessary.

For this task i will aquire front frame rails off another D150 frame, slice and narrow them longitudinally so i can fit them inside the factory rails.

Next problem is, that the crossmember is too wide. Like 4-5″ too wide.

All i know is that the D150s frames outside width is roughly the same as the 1500s frame INSIDE width. Assuming 60mm depth of the frame rail it’s 4.7″ difference in total.

No real problem with that BUT the steering rack. I will overcome that… dunno how yet, maybe a Woodward steering rack.

Cleaning out the hallway


We need some space here. Throw out everything you can but the Rum!

IMG_20160809_185039

Pardon the ultra-crappy cell phone pic. Don’t ever try to use a Blackberry for any photographic work like i do…

Something is coming up. I don’t yet know how to move it up the ramp to my shop but i will get it done somehow.
