baaudio Posted December 12, 2011 Report Share Posted December 12, 2011 85 and 86 are the triggers. One must see +12v and the other Ground. It doesn't matter which. Then 87a and 87 are inputs and 30 is the output. When the relay is not triggered 87a and 30 are connected. Once the relay is triggered 87 and 30 are connected. You can do all sorts of shit with relays. Most of your switches in your car are triggers for relays in fact. All with very similar connections. Most are - triggers to the relay to prevent shorts in wiring. Learning how to use relays has been one of the best things I could learn in car audio.

TLEJ Posted December 12, 2011 Author Report Share Posted December 12, 2011 (edited) Well my relay only has 85, 86, 87, and 30. Also it says 40A on it. Is this safe to wire 85 and 87 straight to my battery? Edited December 12, 2011 by TLEJ Quote Link to comment Share on other sites More sharing options...
baaudio Posted December 12, 2011 Report Share Posted December 12, 2011 not all have an 87a pin. but the one you have is exactly what you need. so no worries Quote Team NWSPL baaudio Build Log 2001 GMC Sierra walkthrough 4 Mechman Elite 370s, 10 AGM batteries, 3 Crossfire XS v2 18s, Crossfire 8k Link to comment Share on other sites More sharing options...
TLEJ Posted December 12, 2011 Author Report Share Posted December 12, 2011 (edited) Also it says 12VDC 40A on it. Is this safe to wire 85 and 87 straight to my battery? What size should I fuse it with? Edited December 12, 2011 by TLEJ Quote Link to comment Share on other sites More sharing options...
baaudio Posted December 12, 2011 Report Share Posted December 12, 2011 i would hook 87 to your battery or any constant source and fuse for about 10-15 amps, i dont see the leds drawing much more then that. and if you want to have lights come on whenever the radio is on just connect pin 85 to the remote wire. otherwise yes you could just put a jumper between 87 to 85 then run one lead to +12v.

TLEJ Posted December 12, 2011 Author Report Share Posted December 12, 2011 Wait, I thought you said do 30 to the remote? haha. I'm trying to get the LEDs to get power straight from the battery (not the remote) , but only turn on if the radio is on. Quote Link to comment Share on other sites More sharing options...
