Kennedy OPS harness

[BamaChief600]

I just received my Kennedy OPS harness and Im looking for a little guidance.


Does the control box take the place of the fuel pump relay? When hooking to the lift pump do I tie into the wiring going to the LP Relay or do I go down to the LP and tie in?

The stock wiring harness should remain untouched.

I mounted the box on the firewall near the underhood fuse relay center. I picked up the hot all the time feed at the back of the fuse/relay center and got my switched power under the dash in the panel mounted to the inside of the firewall.

I mounted the new OPS supplied with the kit in the extra port, under the intake on my newer block. If your block doesn't have this, use a T fitting in the original location. Keep the factory OPS in service to power your gage.

I simply unplugged the factory harness at the lift pump and sealed it off for future use if needed. I then plugged in the pump end of the Kennedy harness to the pump.

The harness works great!

Thanks for the help. I was overthinking the harness. All is well, truck runs nice and another great fix by Mr. Kennedy!
