I have started my build but I need some help. First my setup is a stock lq9 with gmpp cnc l92 heads, comp cam XER287hr, I am going to be using a vic jr intake for efi. A 4l65 with a circle d 5c will be behind it. What I need to know is what aftermarket wiring harness should I go with. Also which gm ecm should I ues for this build.

 

i always hear alot of good things about speartech for a harness
