I knew this day would come...#3 of #3...

JB, help here when and where you can. And never worry about giving back what you got. It’s all good. Just a little help for someone here one day can mean a huge thing for them even if you see it as a little nothing.

With that said.....

On wiring up stuff, splicing into a factory harrnass is mostly only done for “power on” items when the key is in the start and run position. A simple test light will show you the way.

Other wires go to the battery direct. Install/Hook up the ground wire first. Positive last.

The instructions should have the battery cables run and wired last. All the FI sensors should be an EZ run. The hardest being the O2 sensor since you will probably have to drill the exhaust pipe and install the adapter and bung in the tube.

Think before you do anything where the wires are going to run. Sit in front of the car, hood open and get a metal picture of where you want the wires to run along the fire wall or anywhere else for that matter.
