Ok got a used nos kit but it was missing the main realy and of course directions. I've found some info for the 30 amp relay
85-ground
87-Solenoids +12v/Not 87A?
30-Battery +12v
86-Microswitch
This sounds correct for everything, just wanted to make sure on the microswitch . It has 2 terms. One on the bottom is labeled COM is this a ground or positive or is that the one going to the relay? The other is labeled NC so that would either have to goto relay or it get the ground/+12v.
Also should it be a 30amp realy or a 60amp?? Just assumed 30 but I may be wrong.

That sounds good to me... This diagram is basically doing exactly what you need (switching a higher current circuit with a low current switch) but for the fuel pump... Polarity doesn't matter so 85 and 86 can be reversed, as can be with 87 and 30... DO NOT use <U>87a</U> as your solenoid(s) would be open all the time except for WOT (when they would close)... 87 in my diagram would be power to the nitrous solenoid(s) and 85 would be the input 12V+ from the microswitch... As for the relay itself a std. 30A will be just fine... If I wasn't clear or you need anything else just let me know... -Adam

Nice drawing. Where exactly is this relay found?

It's just a standard 30A relay that can be boughten at most stereo shops... Same relay used for adding power doorlocks, starter kills, so they're pretty common and shouldn't be more than ~$5.00 each... Time for class, Peace...
