Hey Gang,

Brief update:

-Corrected "Check Engine" light with 2 12.5 ohm/20 watt resistors (Really they are each comprised of 2 25 ohm 10 watt resistors that I wired in parallel; (Man, does one of them get hot! Melt your shoes hot...)

-Swapped transmission (Supposedly 170k) and rear diff./carrier (160k); pinion and ring looked pristine. Transmission ended up being a bit noisy, and the 3rd gear synchro is unhappy downshifting from 4th...

-Put Duratrac's on from the '80, excellent tire, but I now have wobbles at 65-75 mph.

-A local fellow, Matt from Washougal, fabbed up a set of sliders and a rear bumper. He is a very upright guy, and can build most anything you imagine. (PM me if you want details)

 

Any more details of your resistor fix? This was to correct the codes from using an auto ecu with 5spd trans, correct? Definitely interested since I'm too cheap to buy a 5spd ecu...

 

Hey Fraser, I ended up using two 25 Ohm 10 watt resistors with the end soldered together in parallel; yielding a 13 ohm/20 watt resistor for each set of 2.

I used these, since I was buying 6 of them.

I ended up using such high capacity, since I was burning trough resistors. That only seemed to happen when connecting the 13 ohm resistors to the white or the black wire from the ecu; the yellow doesn't heat up the resistors, and if you clear the codes only 1 Solenoid shift signal will not set off the check engine light.


I used a "Pro" Scan Tool from Harbor Fate to erase the codes, and it actually has been working quite well. You only need to connect 4 wires to the scan tool. I bought a OBDII Y-splitter to dismantle and wire in the glovebox as a permanent connector.


The HF scan tool was also great for watching the o2 sensor in real time, to see a sensor that was getting tired, but not past the ECU's tolerances.



I can take some pics if that helps as well, Oh the Adventure!

 

Yeah pics would be awesome. I still have the pigtails that are supposed to plug into the auto trans under the truck. I wonder if I could make a little plug containing the resistors to simply plug in right there...

 

You could certainly do that (to ground). Remember, if it gets wet it will likely read less than 13 ohm, and perhaps throw a code. I just nested mine behind the ECU.
