Time consuming but a good product
Everything lined up properly and was a bit difficult to install but is expected from a wiring harness. Just takes a bit of time!

DO NOT BUY.
Terrible! Do not use just tried plugging in injectors and the plugs DO NOT WORK! At this point I haven’t even tried plugging anything else in. Need my money back!!!!

Solid Value, NOT A FACTORY REPLACEMENT. PAY ATTENTION.
Ordered as a replacement for a 1999 lm7 5.3 auto rwd truck.It could be made to work, but...Anyway, for the hundred bucks I am keeping it for parts or a stand alone swap later.Its set up for an F body car with the ECU in the cabin, Truck ECU is under hood with the boiling hot engine, its just how GM does things, anyway. Looks to be reasonably well made but read the fine print, it will require changes to things you might not want to deal with.

Save your money
No diagram and won’t return message. Doesn’t fit 5.3 LS swap.
