Default Need help plz L92 harness

Hi
Guys i got my engine L92 2007 yesterday for a new project offroad truck but without engine harness and computer (PCM).
My question is
What harness can be used for this project?
Is Tahoe 2007 with 5.3 vortec harness suit for my engine ? If not what the Alternative Rather than speartech harness because its too costly almost same my engine price

Here is some pics of my engine .






Guys do you know waht does mean this number in below pic

I know what you mean. The speartech harness looks great, but 17 one hundred dollar bills is a little hard to swallow for a harness and PCM. You have a x58 reluctor wheel motor so you will need to get something from a '06 and up. I've seen just a harness on e-bay go for around 800 and then you could source your own PCM for a few hundred more. The only for sure choice out there right now is the speartech harness though that I know of....

I hate to break it to you but that block is a 6.0L like the casting says, not a 6.2L L92.

It is either a L76 or LY6 6.0L. The heads are the same casting as the 6.2L L92 engine. Does it have a car or truck intake? PM me the information on the bar code or send me the VIN for the engine and I can get the details.

Make your own harness its not that difficult. about 8 wires and your up and running. Have to get a stock harness that will work with your sensors/reluctor etc to start with once you figure out exactly what year/model engine you have

I always make my own. Get the schematic and a good meter and go at it. I can't justify spending that much for a harness. Plus you learn the system while you are check or tracing pinouts.

Since it has the car intake on it, powersteering pump looks like a GTO and the L92 heads (casting #12568952 turns into 12582713/14 head) on a 6.0L engine, I would guess that someone already did the h/i swap. What did this come out of? where did you get it?

Why not buy the following part for a 2008 corvette or escalade from GM:
Harness for manual gearbox: $408
Computer: $207
Pedal $75
Add a fuel pump relay and OBDII port and your set to go.

Manual trans, non-VVT engine harness - 15940760
Pedal Assembly - 12835421
ECM - 12612384
Saudi dealers should be able to look up all of these and order them.

Call Scroggin Dickey. They are a dealer. Just because it is not on their site does not mean they do not have it.
