Hello there guys this is a long shot but I’m looking to swap in a Haltech elite 2000 standalone into my 700$ 96 LS400 my ecu is a 89961-50303 with the pins 34P-22P-16P-28P hopefully one of you might have come across some secretly hidden wiring diagram and are able to help me with my predicament I’m looking to get a schematic of the pins on the backside of the ECU for the engine harness so i can mate it to the so called elite 2000 from Haltech i cannot for the life of me seem to find a wiring diagram on my particular ECU/ECM please if anyone has anything helpful it would greatly be appreciated My dreams of making this car badass before January are slowly getting shot down with the project due to me leaving in a few months for the AF so anything helpful would be greatly appreciated-Aaron
