OK so i got a few questions here ....
Do i use teflon tape on all fittings?

I have the zex 82026 and the single stage window switch from daves outlets. Do i need to go get a relay and wire it the way it says to for a normal system?

The purge system brand X daves outlet . Do i just wire that normaly ground then put the live power to one side of the switch ?

The fuel pressure saftey swith how do i tie that in . Kinda friggn lost here?

 

run your kit like it says in the instructions, i have the zex 82027 and i just wired it up like they said but where they say run the noids from pin 3 or 87 you want to run that wire to another relay pin 86 or 2. then wire your window switch like it says but run the activation wire off the ws to the fpss to pin 85 or 1 on the second relay . the second relay will have 12v battery on pin 30 or 5 and run pin 87 or 3 to the noids and it will all work right. i hope this helps if u have a problem figuring this out just pm me and i should be able to help....
