Default Best Aftermarket Harness Ever

I'm not sure how many of you have dealt with PSI but I bought a full harness for my LS powered Jeep from John over there and it couldn't have gone better. Any issues I've had (all self inflicted BTW) John was right there to help...even on Saturday and Sunday!

I just had such a good experience with PSI that I felt the need to let them and everyone else know it!

Thanks John for everything!

You wont be disappointed. The hardest part of the install was drilling the hole. Lol

Any up close pictures of your harness? What was it wrapped in? Excess wire loops on sme runs or just the right length? Exposed wire anywhere or is everything in loom? Fuse panel included? Cost?

The fuse panel is included. There was no exposed wire except for the wires u need to connect to key on, ground etc. Cost was right around $500 and they tested the computer and gas pedal to make sure it all worked.

Good information to hear.

Did you send them the throttle body, pedal and ecm for testing?

Hmmm. Good to know! I've been pretty dead-set on doing my own harness (largely because I expect that the knowledge will help me when troubleshooting), but it's definitely helpful to know that there are vendors out there doing good-quality work... If for some reason I decide it's too much grief to do my own, I'll keep them in mind...

I havent installed the harness yet as I'm not at that step yet but I have to agree with previous comments the build quality of the harness is very impressive.

Jon, your pics aren't showing up. Noticed that in one of your other posts as well.

Thanks Boostnut. Not sure why that is, having issues with the forum uploading them for some reason. Saw this on some other postings, has anyone else had this issue?

Thanks for the review....I was considering modifying my own, but figured for a couple hundred more, I could avoid a potential serious headache LOL. I will probably be contacting PSI when the time comes.

I will echo all of the great reviews for PSI

I used their harness on my Chuck Wagon build and it was very well put together. It was nice to have been able to drill a hole, plug and play.

Upload them to photobucket or imageshack and then insert the IMG code in the post. Works every time

Glad to hear, I talked to him a couple times through email because I plan to get their harness for my ls1 notch. Was also surprised on his reply within an hour on a Sunday.
