    700R4 TCC with and without brake switch

    The ECU and wiring kit I got doesn't have a connection for the brake switch that disengages the TCC. The rebuilt transmission is supposed to be for a 1991, which had the brake switch. The pink wire on the transmission plug goes to the ECU. Problem is, after getting the engine running and...

    RETRO-Mod: Intermittent wipers in your 1976?-83 squarebody

    I put a newer tilt column into my 82, with wiper and dimmer. Installing the intermittent module just required plugging it in between the column plug for the wipers and the wiring harness plug that went to the original dash wiper switch. (If only GM had used that sort of common sense for the...

    Retrofit normal washer pump in place of wiper motor one?

    At some unknown time in the past, the wiper motor on my 82 was replaced. Of course it has that mechanical cam actuated abomination of engineering for a washer pump - the design that has a 100% failure rate. Of course it has failed. Makes a single noise then nothing, no wimpy, periodic...

    Replaced ashtray with 3x12V and 2xUSB

    Got rid of the ashtray in 1982 GMC truck by 3D printing a piece to hold the 3 sockets and 2 USB charging ports from that thing in the other picture. Pretty decent for charging. My Galaxy S4 will pull 900ma from the USB ports. If you want one to hack for similar projects, google Bell Automotive...

    Shifter mods for 700R4 upgrade?

    The tilt column I got was *supposed to be* from a post '82 truck with a 700R4. I didn't pull it myself, and none of the trucks in that yard had instrument clusters, or engines and transmissions, so no way to verify without looking up lots of VINs - course data like transmission type for 1980's...

    Shifter mods for 700R4 upgrade?

    That's the problem. I NEED manual low for rolling down steep roads with a couple thousand pounds of stuff on the bed. This is going to be my rig for hauling stuff like metal lathes.

    Shifter mods for 700R4 upgrade?

    I need to get the truck going pretty soon. I'm going to see if I can adjust the linkage so it sits in the right position for Drive/Overdrive.

    3D printed dash screw anchor nut.

    Installed my new dash pad yesterday and needed one of those oval plastic things for the passenger side. Didn't even bother looking up cost for a new one until just now. Didn't want to wait, or pay for shipping on one wee little part, so I modeled and printed this pretty quick. I really...

    Shifter mods for 700R4 upgrade?

    What I really need is the 700R4 shifter quadrant from a post-1982 square body column. I swapped in a later tilt column that was supposed to have come from a truck with a 700R4 but it obviously did not because I cannot shift down into the 1 position and the other stops aren't quite right. I've...

    TBI wiring harness recommendations?

    I've had enough mucking about with the old 1991 wiring harness and it not working in the 1982. One of those can't find a #%#ed thing wrong with it but it still doesn't work situations. Pour fuel down it and it runs but the system will not open the injectors. Spent a ton of $ replacing parts...

    What ECMS interchange with 1991 Chevy pickup?

    350, gmt400. That's my donor truck. Is there a way to test an ECM to verify it's good?

    Troubleshooting Your TBI Fuel Injection System

    Dead link. :( Is the check engine light required to get the blankety-blank thing to trigger the injectors? If so, then I'll need to get that hooked up on my truck.

    What ECMS interchange with 1991 Chevy pickup?

    What other ECMs have the same hardware as used in a 1991 C3500 standard cab, into which I could swap the chips?

    Cause of injectors not working?

    I've installed new injectors, new fuel pump regulator diaphragm and spring, swapped the 1982 tank for a 1987-1991 Suburban tank and pump. I have fuel going to and through the regulator, enough that it's soaking through the gasket on the throttle body. I have power to and through the...

    TBI fuel pump that'll fit 1982 tank?

    It's an Airtex E8887. I mounted it inside the right frame rail at its lowest point so it's below the bottom of the fuel tank. It doesn't have a reservoir and low pressure pump between the tank and Airtex pump. I also primed it by wrapping a rag around an air blower and pressurized the tank.

    TBI fuel pump that'll fit 1982 tank?

    Which years and models of GM truck will have an in-tank TBI fuel pump that'll directly swap into the tank on my 1982 1-ton dually flatbed? The inline pump I bought new is supposed to be a 15 psi, which should be enough, but even after installing new injectors, regulator diaphragm and spring...

    Part # for AC-Delco TBI kit with injectors?

    The seller kept the original box so I still don't have the kit part number. Here's the number on the instruction sheet, which likely won't be very useful 08050-678-1

    Part # for AC-Delco TBI kit with injectors?

    Rock Auto shows no complete kits like that, with injectors and regulator spring. A nearby GM dealer said their system showed that they serviced TBI's with a complete upper unit, no longer available. I went ahead and bought that for $125.86, free shipping. When I get it I shall post the part...

    Part # for AC-Delco TBI kit with injectors?

    Does anyone know the part number for the TBI rebuild kit with injectors and fuel pressure regulator spring, as shown in the attached image? The seller of this was careful to not include the part number. I want to shop around to see who has the best price. Took the top off the TBI on the 91...

    Replacing ashtray with more 12v and USB ports

    If I had my 3D printer done I'd use it to make a custom piece that would hold these parts and attach to the tip out. I could CNC mill something... I'm thinking of a rearview video screen in the empty pocket in the dash panel. I'd have it on all the time instead of just when in reverse. Would be...

    Replacing ashtray with more 12v and USB ports

    K-Mart threw me some "surprise points" so I bagged a Bell Automotive 22-1-39279-8 5 outlet power station with three 12v sockets and a pair of USB ports. Cost $5.99 for shipping. Soon as it arrived I had it taken apart, got the ashtray out of the 82 GMC and with a bit of Cardboard Aided...

    Where can I find +12V hot in run and start?

    Now I just need to rotate all the plug wires one position on the cap so the module isn't aimed at the firewall and it *should* be able to run. Then I can get on with re-assembling the front end. Took the grille, radiator and support etc all out to make it easier to do the swap and to work on...

    Where can I find +12V hot in run and start?

    Turned out to be not enough power. :P Hooked up a fully charged battery and now it is right.

    Where can I find +12V hot in run and start?

    According to the attached image, terminal I1 is supposed to be hot in both Run and Start but it's only hot in Run. I just put a new switch in, same thing as the old switch. 1987 tilt column in a 1982, 1991 TBI conversion (350 V8 and 700R4). Nothing on the fuse block is hot in Start. The large...

    1991 C/K ALDL wire colors & positions?

    Black/white and white/black stay where they are. SES light wire in position D.Position M for serial data not used for V6 or V8 and some diagrams I've found show an orange wire foe serial data. I have an orange wire tagged ALDL... so the other serial data position is E. Now what I have left is...
