I'm about to pull the trigger on a 62k mile LQ9 to swap into my IROC, but it comes without a harness. The junk yard that I'm getting the motor from said that they can't even get me one... they're always cut when the motors are pulled.

So, I'm going to need to look for a harness on my own. Anybody care to educate me on harness differences between LS1/LS2/LQ4/LQ9/ blah blah blah?

In the end I will likely have L92 heads and an LS3 intake/injectors, but that's subject to change 20 times too.

 

I would pick up a harness from an fbody because they fit better with fbody accessories and intakes. I bought mine from someone on LS1tech (and a member here come to find out) for $200 shipped and un-cut.

 

Are you doing drive by wire or cable? That will play into what you need for a harness as well. but fbody is definitely the way I'd go as well if you're trying to stay as clean as possible with routing without modifying (trucks are nice but will require a bit of trimming if you want them routed nicely, not to mention different plugs for the injectors). Stay away from 98 fbodies though, they are an oddball year when it comes to tuning and not as well supported.

 

Good to know, thanks.

I'm sure I'll be going with a cable operated throttle body, so the f-body harness sounds like the way to go. They should be plentiful too.

 

Ya if you put up a wanted thread in the LS1tech marketplace you will have multiple people respond within days.

 

definitely some amazing deals to be found over there. got me a set of rebuilt heads for $150/shipped/complete.

hunting a harness myself, but no money to pull the trigger yet...

 

I have a harness from an 02 Camaro if you are interested. I was going to use it for my swap, but went with Speartech instead.

 

Ill buy the cut harness off of you
