Auxillary Reverse Lights - 5/5/2008 2:06:14 PM    c0a8l0v6i8n9 Posts: 178 Joined: 1/6/2008 Status: offline Ok so today I installed two auxillary reverse lights and I have them set to come on with the reverse lights. I was wondering if anyone had a wiring diagram that will allow me to have the lights: 1. Come on with the reverse lights. 2. Have them come on with a switch also when not in reverse. Thank you. _____________________________ 1994 4 Door S10 Blazer, 4.3 VIN "W", 95,xxx miles, Xenon Lights, Driving Lights, Pioneer DEH-3900MP, Infinity Kappa 462.7CFP, Kenwood KFC-1682ie. Post #: 1

RE: Auxillary Reverse Lights - 5/5/2008 2:14:58 PM    drperry Posts: 3896 Joined: 1/12/2007 From: GP AB CA Status: offline You ARE using a relay to power those lights, right? The factory wiring isn't built for much extra power than the stock lights... If you ARE using a relay, like you should be, you can just run a wire to the trip pin of the relay to a switch in the front of the truck... _____________________________ (in reply to c0a8l0v6i8n9) Post #: 2

Status: online Not a good idea.  It really would be better to run a new wires for the lights, use the reverse light as an input to activate a relay.  That way the relay powers your aux lights with a seperate power source.  If you need help on that I can show you where to look. _____________________________ 85 S10 Blazer 4x4, 2 door, undergoing 350 swap, 3" BL, 33''''s 89 Jimmy 4x4, 2 door, 4.3/auto (in reply to c0a8l0v6i8n9) Post #: 4

RE: Auxillary Reverse Lights - 5/6/2008 3:33:02 AM    drperry Posts: 3896 Joined: 1/12/2007 From: GP AB CA Status: offline Get a $5 relay from a parts shop and you won't have an issue... most of those are good for 30 amps at least... I've bought some lights with relays that are less than an amp away from what the lights pull. The relay for my driving lights is known as "over kill" but I know I'll never have a problem with it getting too hot The factory wiring is 16, 18, or 20 (I can't remember which) guage wire over a decently long run... It's really not made to power two sets of lights. If you take out your normal reverse lights, you might be okay... 50 or so watts for the factory lights (about 25 watts each) and another 110 watts for the extra lights (55 watts each) that's 160 watts... That's 13.3 amps @ 12 volts... That's pushing it over that length for 16 and 18, while pulling 2 amps MORE than what 20 guage is rated for. There's a reason your fuses are rated at what they are... To prevent the wiring from melting You might not have any immediate issues, since when the truck is running, and you're putting out 14 volts, the amp draw is a little less. 11.43 amps, infact... .43 amps over what 20 guage wire is rated to. Get a relay... There's 2 reasons for it... #1 safety #2 way easier to get it switched like you want. If you have an amp/sub combo in the back, run your power wires to there. _____________________________ (in reply to 2002XTREME) Post #: 7

RE: Auxillary Reverse Lights - 5/6/2008 12:22:46 PM    c0a8l0v6i8n9 Posts: 178 Joined: 1/6/2008 Status: offline So yea I will run the wires down the left side next no the trailer wire harness. Im assuming that I will need power going to the switch, and then a wire going from the switch to the lights. Now where should I incoporate the relay, if someone has a good diagram that will help. Thank you all for the help so far. _____________________________ 1994 4 Door S10 Blazer, 4.3 VIN "W", 95,xxx miles, Xenon Lights, Driving Lights, Pioneer DEH-3900MP, Infinity Kappa 462.7CFP, Kenwood KFC-1682ie.

RE: Auxillary Reverse Lights - 5/6/2008 2:50:46 PM    neo71665 Posts: 304 Joined: 12/18/2007 Status: offline well hell My first one not good enough? With the switch on they will turn on and off when you put the truck in reverse and won't come on any other time. I can also draw it up where with either a 2 pole double throw switch you can turn them on any time but still be switched on/off with the factory lights. _____________________________ 1987 s-10 blazer 4x4, 2.8, 700r4, np207, 3.73 gears with a few mods.

Status: online The only problem I see with that would that the switch needs to be able to handle the current draw of the lights.  Generally what you are trying to avoid when using a relay.   _____________________________ 85 S10 Blazer 4x4, 2 door, undergoing 350 swap, 3" BL, 33''''s 89 Jimmy 4x4, 2 door, 4.3/auto (in reply to neo71665) Post #: 10

SO, I would buy THIS and save yourself the trouble.  Or, look at everything that comes in that kit, listen to these guys that know what they're talkin about, and set it up yourself! _____________________________ 2000 Blazer 4d LS 4x4 - 265/70/15 General Grabber AT2s - Hunter Brush Guard - Surco Roof Rack with IPF 868s - 1.5'' Shackle + Tbar - 2'' BL (in reply to c0a8l0v6i8n9) Post #: 12

RE: Auxillary Reverse Lights - 5/7/2008 1:33:05 AM    drperry Posts: 3896 Joined: 1/12/2007 From: GP AB CA Status: offline Make sure you pick a decent switch, otherwise you're gonna be turning on the reverse lights at the same time with that one... You should only need the diode on the wire that turns on the extra lights when you put it in reverse... I think. _____________________________ (in reply to Blazin_Jason) Post #: 14

RE: Auxillary Reverse Lights - 5/7/2008 1:33:50 AM    neo71665 Posts: 304 Joined: 12/18/2007 Status: offline On mine I'm trying to draw it with only one power wire to keep the wire running down and hopefully make it easier. And yes the main draw back is having to use a switch big enough to handle the draw of the lights but with a second relay I can fix that problem, lol. Hopefully this one will help more. The double pole double throw switch (one with 2 ons and a center off) can be replaced with 2 switches if you can't find one but 99% of alll auto parts stores I've been in carry them. _____________________________ 1987 s-10 blazer 4x4, 2.8, 700r4, np207, 3.73 gears with a few mods.
