Where do you guys connect or recommend connecting the switched ignition 12V wire for the relay that controls the fuel and nitrous solenoids?

I'll also need another ignition source for the purge solenoid... or should I just connect the solenoids on one source? I was thinking of wireing them together, but am concerned about the amps drawn. What do you guys recommend?

Thanks in advance...

 

They armed through relays so the amp draw is not a problem since the power is pulled from the battery through the relay to the noid. I wired all mine in to the ignition wire for the headunit.

 

hmmm I see, but the purge kit didnt come with a relay. It only has two wires: one for the ground and one that goes to the switch and then exits to a 12V ignition. The noid will get its (+) power from this connection. I was thinking of wireing the noid to a fuse in the instrument panel fuse box. Maybe to the windshield wiper fuse (25A) which only works when the truck is in the ON position (ignition). Would this work?

 

I always put my purge on it's own relay. you could do the wipers thing but that's your choice.

What would I have to do in order to use a relay for the purge? Or will the wiper fuse work???

I just need an ignition source to send power to the purge noid. It will only draw amp when I click the activation switch, plus Im not gonna be purging and using the wipers at the same time... so I will never over charge the wipers fuse and pop it, but do you think it will work?

btw, the purge kit is an edlebrock part # 72176
