LSA engine harness rework
 

Can you guys give me some recommendations on reworking a factory LSA harness to use in my 1960 Impala.

Attachment 71653

I'm currently stuffing an Art Morrison chassis under it and had been running a 24x 0411 ecm with a speed density tune. I'm going to swap the crank to a 58x and would like to run the E67 ecm and harness that I have out of my Road Race CTS-V

Obviously I'd like a quality harness rework with a nice sealed fuse box

Thanks for the help

Are you looking to rework it yourself or farming it out to someone?

I'd prefer to have someone else do it.

Speartech does a nice job on reworks.

I am going to have speartech do mine also. Seemed real knowledgeable

X3 for speartech, sweet ride!!

Hey,
nice to see you over here, didn't know you had a sweet Impala. Speartech would get my vote.

Any pro or cons if I went with the GM Performance LSA harness instead?

I like the sealed fuse box and price wise it's comparable to a rework since I have the pedal, o2's and MAF already.

Thanks for the replies

I've used Speartech and HotWire, both excellent results.


Jeff-

If you decide to use the harness and ECM the fuel requirement is a bit odd. We have the fix for that when using a GM ZL1 fuel module (the best.)
