Anybody use the aftermarket engine harness that Trick or CP performance sells. Are all the wires you need in the harness or did you find that you had to run seperate ones?

We make our own wiring harnesses that are a Merc replacement. We have engine only, Efi harness and a harness that runs up to the dash. Tyler 8103242720.

with all due respect to all the other pro's, i ve yet to see anything beat a merc harness. which is why you have this thread to begin with.
if there is one out ther i would like to know of it and maybe you guys can shoot me an e-mail or p,m about it.

good luck to all

My problem is I got rid of my EFI and the harness went with it. I now need a new harness but not sure which to use. New motor is a carbed 509.

merc harness for a gen IV b.b

Only problem with that is the GEN IV harness plugs in at the exhaust elbow on the shift bracket. My harness from gauges to motor is at the center of the transom with about 1 foot of tail (won't reach). It was previously set up for a GEN V EFI that plugs in at the rear of the motor.

I used a $69 harness from Fred on my carbed big block,did not have to run any additional wires.Plug fit was good,no problems.
