I bought a 2002 corvette z06 engine with wiring harness, ecu, pedal, etc. I've gotten it into my 99 tahoe but I can't find a proper Fuse Block connector pinout. I purchased access to alldatadiy.com but it has the wrong colors and I've searched this forum with no success. If someone has the pinouts that would be awesome for its the last thing that needs wired. The connector is C2 I believe and here are the pins with colors:

a7 pnk
a10 blk/wht
a12 pnk
f1 blk
f2 pink
f3 ppl

f9 blu
f10 lt blu
f11 pnk
f12 grn

The colors might be slightly off, ie grn might be dk grn. but I know that f3,ppl is the crank power.

Thanks for the help.

^^^ Thanks for the link. But the pins don't match up.

That will be useful if I end up needing to trace where all the wires go, but I hope there is a pinout that matches my harness.

Maybe post a picture of the connector? Are you 100% sure of the donor vehicle?

I'm not 100% sure of the donor. The seller did a nice job pulling the engine and had a vid of the engine running in the vette. They said it was a '02 z06. I have the ecu, if there is a way to identify it through the ecu or block, I can try that.

Here are the pics of the connector:

Same thing I'm working with. Is the fuse panel in question the under hood one or the one in the cabin? The blocks are very similar in construction but very different in wire schematic.

slacker247

It's the engine harness and there are only three connectors coming from the harness. 2 round C149 and C150 and then the block connector in the photo. I've tried matching it with the body? fuse connector and there is no match. I know that the ppl wire F3 is the starter wire. It cranks, but I don't believe that the ecu is getting power.

what year make and model is the tahoe? does it have 4wd? and an email address to get them to you?

slacker247

I'm might have spoke a little confusingly. My bad. I'm looking for the pinout on the corvette fuse block. I have the fsm for the tahoe. Thanks for the offer tho.

send me your email address, the file will need to be opened in internet explorer.

slacker247

yeah, I already have those and they don't match up. I did notice a number in the Connector part information box. Is that the PCM number? if so here is the number off of my pcm:12200411

I guess the questions is are you sure it was a 2002 z06? Did the ecu come with all of it? Can you have info pulled off the ecu to verify it was a 2002 z06?

slacker247

I'm not a 100% sure, but the engine came with pcm, wiring harness, throttle control module, pedal, maf, and plastic engine covers, supposedly from the same car, well the harness was and still is attached to the engine. The pics on the net match the engine covers to the z06 C5 vette. The pcm #12200411 seems to match 2001-2003 but most ref the 2003 z06 car. My guess is there was a change over some time late 2002 early 2003 that changed the pinouts. But I can't find a 2003 pinout, so I don't know.

I always seem to get stuck with the odd ball stuff :/

I just sent you the 2003 pinouts. They are different because it would have giving the same pinouts as the last one, but it was not the same.

slacker247

hmmm.. The 03 doesn't match either. Frustrating. I'm using the Starter Solenoid Crank voltage (ppl) to start the id. According to the two tabs coming off the connector the crank is F3 but the diagrams you are sending me are saying it should be A10. But either doesn't match the other pins. Most are said to not be used But I have wires there and where it says there's a wire, I don't have one. Maybe it's an '01.

I wonder if I can get a hold of the seller and get the VIN.

mcdonald77

iTrader: (21)

no clue, the 2000 and 01 are the same as ive sent you.

slacker247

ok, I got the vin:1G1YY12S125128696 it's definitely what I've been looking at 2002 z06. So, now I'm totally confused as to why the wires don't match.

I guess I'll have to do it the hard way...
