FYI - the ACCEL harness is the same no matter the application with the exception of the ignition harness.

This is why some might find it to be a poor fit. In my case I installed it on a 400 cid Pontiac motor with a World Products EFI manifold.

I admit that other harnesses I have installed were designed for the specific engine system and that would explain why there is less bulk and issues with those.

On another note - We have this one in and running. Other than final tuning we are looking into another possible ECM fault as it won't turn on Fan 1 - No matter where the program is set for turn on temp - it won't initiate the ground.

We replaced the original ECM from the start due to a bad driver on #1. That one has been returned and I'll swap the loaner out and hopefully solve the #1 fan problem with a possible bad output on this ECM.

Otherwise - it runs very smooth. I have made a couple of hard runs with a G tech. The car weighs in at 3,625 without driver or passenger. We are running a 700R4 with 2:41 rear gears (you read that right). It has a 2,600 stall converter. It ripped a 5.3 0-60 just blowing the rear tires off and a 13.9 1/4. This comes from a car that stock ran a 8 second 0-60 and a 17 second 1/4 mile.

It is lean on hard acceleration and I'm getting spark knock. I believe after fixing that and getting a handle on launching it those numbers will fall.

The best part.....1,500 RPM at 70 mph baby...and smooth as glass in all gears while just cruising. We may push 30 mpg out of this puppy if we stay out of the gas pedal!
