Default anyone building mega squirt 3 harnesses??

does anyone build ms3 ms3x harnesses?? I have both ms3 and ms3x harnesses, relay board and relay board cable and my stock 2011 express 4.8 harness. I would rather have someone do it that's been thru this before.

I have built several. It's not hard. You can do it.

Alldata is the best place for pin outs. If you feel like it's over your head let me know I could help.

EFI Source do harnesses ?

Matt does packages too...so presumably he could supply just the harness
