Agreed, and I put the temperature gauge front and center so as to easily keep an eye on it (although I eventually to relocate the temp sender as it's near where the heater core valve should be and...

Hi 89S10_Project,

The fan is a Volvo, and I've got it mostly sorted. 30A is fine for each speed (I used an inline fuse holder to test it, it didn't blow a 30A, so should be fine). I'm using a...

Two things that could be important to know:

I basically rewired the ignition and fuel system from scratch using the schematic.

When installing a mechanical oil pressure gauge, I removed the...

OK! Been tinkering with this for awhile in my spare time (to get it street legal, install fan solenoids, oil/temp gauges, replace rear diff fluid, etc.). Finally got it out on the road, and it's a...

Hi Six_Shooter,

Turns out I didn't ground D3 to a common ground (that was C8, I wrote that in error).

Did some more checking, located the actual ECT (it's to the left of the thermostat) and...

OK, thank you.

The fan is probably dual speed. I will read up on those.

EDIT: The CTS I'm looking at is evidently for the GAUGE, per https://www.youtube.com/watch?v=un2neiiNk8c

I'll get a...

OK Six Shooter, I need a bit more help if you're willing... I'm trying to figure out how the coolant temperature sensor is supposed to be wired into the ECM, and how the fan control is supposed to...

IT'S ALIVE!!! :rockon:

Last wire to connect was the main coil feed, once I figured that out, it popped right off. Vroom-vroom! There's still a few wires left unidentified, but maybe they aren't...

OK, the vehicle is a '92 (and the donor motor/TBI system is likely the same vintage) so then direct power from the ignition switch to the injectors/coil/ECM is not unusual, that's good to know.

I...

OK, I'm going through every single connection, and rewiring everything from scratch. Here's why, take a look at the existing wiring:

10588


10585

10586

10587

OK, so it looks like the previous owner punked this TBI setup pretty well.

I'm going to have to go through the whole thing, pin by pin and verify each connection is correct and possibly wire each...

I inverted the colors so I can print them out and more easily make notes on them. This might help someone else, so I'm putting them here (I don't want to put them in the main ECM/PCM diagram section...

Roger that, tomorrow I'm going to trace wires according that diagram and see if anything is amiss.

Any suggestions?

Thanks in advance.

OK, if I check the wiring against this:

and it matches, then I will have...

Based on the number of pan bolts, the position of the connector, and the location of the ID tag, I'm pretty sure it's a 4L80E. Circle on the bottom of the pan matches similar pans found in a web...

Everything matches the transmission here (ID tag is in the same place, same for electrical connectors, 17 pan bolts) http://www.moveras.com/TechnicalSupport/QuickReference/TechnicalSpecs4L80E.aspx

Some more observations and pics. First, the pan has 17 bolts.

Whoops, I must have tried to read that BCC code upside down from the picture, thanks for catching that.

It's really tight under there, so trying to get a good look is challenging.

BUT, the...

OK, here's some more info. I was told the donor motor came from a Silverado. Here's pix of some partz:

Also, 16127487 was stamped on the inside of the ECM cover.

Wow, you guys are great. Seriously!

I'll pop the cover of that chip and take photos tomorrow, and also see if I can identify the transmission. In the meantime, this is the only thing with the...

Thanks, but I don't think that's my ECM. The plugs don't look like the one here:

So, I bought myself a vehicle with a GM 350 TBI conversion and what I was told is a 460le transmission. Looks like it came off a donor vehicle (not an aftermarket TBI).

The previous owner screwed...
