Any updates on your swap and wiring?
Yes lots of new updates. I have finally got the transmission and transfer case reinstalled. The transmission is a hybrid of the original H3 trans and the 09 Silverado trans that I purchased from a salvage yard. I couldn't use the silverado trans as is because of the pan interference with the driveshaft as CaseyS pointed out. I also still needed an input speed sensor to make the computer that I will be using happy. I ended up swapping the pump, input drum/shaft, speed sensor, torque converter, and bellhousing from the Silverado trans into the H3 trans. My local transmission guy swapped over the parts and installed a corvette 1-2 shift servo for only $50 which was well worth me not possibly screwing something up by doing it myself.
I added the wiring for the input speed senor by removing the wires and pins from the Silverado trans internal wiring harness and and adding them to the H3 trans. There are two pins that have to be added to the large external plug. Here's what it looks like before
The internal part of the plug already had provisions to add the additional pins so that part was pretty simple. 04colyZQ8 provided me with a diagram that showed the correct location to add the pins.
Two small holes had to be drilled in the top part of the plug so the pins could protrude through. I had to be very careful to drill them in just the right location and everything went back together perfectly, (My phone died so I didnt get any pics of this step) The third wire was a +12V supply to the sensor and I soldered that to the +12V wire in the H3 trans harness. Here's a pic of the added sensor (top right corner).
Since my H3 is a 06 model it came with the plastic shift fork in the transfer case. I was having some issues with it not wanting to lock in 4x4 so I decided to go ahead and swap to a metal shift fork while I had the t-case out. The swap was easier than I thought and only took about 30 mins from start to finsh since I already had the case out. Here's some pics of the badly worn fork
For the fuel lines I used Dorman nylon lines and connectors. I purchased all the needed lines and connectors from rock auto for under $40. Looks stock since GM uses nylon lines on these engines
The biggest issue and hold up so far has been with the programing of the PCM. GM suddenly and unexpectedly changed the capabilities of the programming software (04colyZQ8 can probably elaborate on this part). The good news is that everything should be figured out now and the programing will be finished in the next few days if everything goes to plan.
