Rep Power: 328

Hola, I need to hook up a relay to my neons. I want to run the activation line to my cig lighter, which numbers on the relay do I hook the neon, 12v from the battery, and the trip wire up to? THe relay is one of those square black ones. Thanks!

If I wasn't 5 degrees out and I wasn't getting 12" of snow today I'd go out and look.

I dunno what the numbers were and all that .... but heres the general idea of how to hook it up.

I just threw in a TV and PS2 for examples ......

Here's how your relay should wire up. #85 goes to your cigarette lighter (your + trigger wire) #86 goes to ground. #30 goes to 12 V+ (battery) #87 goes to the neon as your new swithced source of 12 volts.
