alright, i've been wondering this ever since i took the dashboard out of my RX-7. im going to upgrade to a haltech for a fact, more than likely a PS1000. i've seen ppl's builds and write ups when they swapped up to a haltech ECU and they just tell you the wiring from the haltech to the engine components. so my question is the other 2 remaining plugs that went into the factory ECU, what happens to them? i assume for the haltech you'll splice into them to get the signal to the dash, but i wasnt sure if ppl used the factory stuff, or made a new loom to go to the dashboard. or you just run fresh wiring from the sensors to the dash. this has always been one question that ive been sitting on for a long time but havnt found an answer to yet. thanks guys.

P.S. i removed the dash to lay down dynamat and route the batt relocation stuff.

The remaing plugs will just be left alone other than maybe connecting haltech wires into them.

Yes you assumed correctly. There will be wires in those remaining plugs you will have to splice into.

As long as the factory wiring is intact there should be no reason for replacing. I used all factory wiring except for the engine harness wich I replaced with the haltech harness.
