I did just to clean up the area. As I remember it was only about $20
so the pair block kit though is necessary when using the nitrous harness?
I really don't know. At a guess if you unplugged it and you disabled it in the ecu it would be fine
reason for asking cuz this is whats stated in the nitrous harness install instructions
**WARNING**: For off-road use only!!!! You must have your ECU re-flashed and setup for NOS control BEFORE you install this nitrous harness. Failure to do so will damage your engine, as well as nitrous solenoid. You must install a PAIR blockoff kit prior to using the PAIR circuit to control your nitrous activation as this harness renders the PAIR system in active.
eBay also has the plates
I guess you need it. I really didn't know
You can buy a harness for ECU nitrous contol, but all it is doing is doing for activation is grounding either the mode up or mode down button input to the ECU (same as pushing the button yourself). You can do it with a switch or with a different momentary button to ground if you like. You can have a three position switch to have "auto", "manual" and "off" if you like.
Then for the output you simply use the two wires from the PAIR to activate a relay, then use the relay to supply power (or ground) to your solenoid.
If you buy the harness it is mostly plug and play, but if you want things set up a little differently then you are doing your own work anyway. $10 gets you a switch and relay.
