Ls2 harness Howell EFI?

[paulgurley]

Has anyone used their harnesses?

I'm putting an 05 gto Ls2/t56 in my 68 camaro and am now looking for a harness and tune for the cam I put in.

There's so many options for harnesses and ecu flashing, but they can load a tune to my ecu with my cam specs as well so I'm leaning towards them for my harness and ecu, and I just wanted to see if anyone has used any of their products.

Well respected vendor. Former GM engineer. Been around for years!

You could certainly do a lot worse!

The harness that you linked is an E38 harness. For your application you need an E40 harness. Many harness manufacturers do not build a harness for that application. I do not know if Howell builds one or not. They may. You will have to give them an email or call, I would think that they build it. Esp. With the experience and reputation he has.

We do support that ECM and have built 100s of those harnesses since we are one of the few that support it. Here is a couple links. The first one will let you know how we build harnesses, the second is the harness we build.

Howell makes a nice harness for sure. A friend of mine is a Dealer and he uses them on all of his LS swaps. The only gripe he has with them is their turn around time leaves alot to be desired. To their credit tho, he has told me when he is really pressed for the harness' he has needed asap they moved em up and got em out quick. My friend (the dealer) uses them religiously and knows to order them well in advance if at all possible. Reliability and custom lengths are not an issue either.

With that said if you don't have a friend like I do who is a dealer then I (if I were in your shoes) would look to one of the sponsors here as most are stand up PLUS you have the added advantage of them being available for you outside of business hours on here. Most of them are more than just businessmen...they are car guys too and love to help. You sir are in a win win situation if you ask me! :D Hope this helps.
