    Never ceases to amaze........the intolerance, indeed ignorance of individuals who post rude, arrogant, mindless, moronic comments unnecessarily. This guy goes to the trouble of creating an informative video when he is clearly suffering from a malady, and the brain dead’s can only comment on his blocked nose. You Tube caters for everyone, amateurs and experts alike, used with caution and a little wisdom it frequently provides much needed assistance. An invaluable source of reference when faced with a problem but having to sift through the garbage for additional information is time consuming due to the keyboard warriors who enjoy the sound of their own voice no doubt, their right to exercise intolerance. The negative comments do nothing to encourage others to make a worthwhile instructional contribution on KZread.

I also want to wire up a wig wag relay for some lights. The pins are marked L - X - and P. Is the P for power in and the L and X for each of the lights? Your help would be greatly appreciated.

    Thanks for the video although I'm a little unsure about number 87 if you not running the relay from your ign switch or toggle switch , I have a elec cooling fan in my old 69 truck it came with a fan controller they did not include a relay in the fan it's power from the battery to a fuse then from the fuse to the controller , the fan is wired into the controller and when the probe reaches a set temp fan turns on . I know I can go battery to fuse then fuse out to 30 85 is grounded but since I'm not running a toggle or flip switch would I go 86 or 87 to the fan controller ? I see how the relay works like if I wanted to mount some cab lights on the roof or fog lights etc . The POS and neg of the fan go into the fan controller the power for the controller now is just right from the battery to the controller at idle at stop light it really puts a hurt on the alternator

    It actually seems like the controller is a relay since 30 is the power the temp probe is 86 when it gets to temp desired it turns on triggering 87 we're the fans are connected to although if that's the case don't know why I have such power loss I'm also running a elec fuel pump only draws 4/5 amps

  • @Crusty_Camper

    @Crusty_Camper

    4 жыл бұрын

    I had to do exactly that for my car horn. What I did was to connect the fused 12v supply to terminals 30 and 86. Terminal 87 went to the accessory ( in my case, the horn ) and 85 was effectively switched by the horn button. When the horn button was not pressed, the power across 86 - 85 was not a complete circuit, so no power crossed between 30 and 87. When the ground was completed by the switch ( horn button ), the trigger circuit 86-85 was completed and this triggered power to cross from 30 to 87. It works fine.

    Hi, I wired up some backup/aux lights before I saw the video and have done it as follows: # 30 to 12v bat. # 87 to lights (grounded) # 85 from reverse light wire # 86 to ground The lights come on when in reverse, in order to use them as auxiliary lights I added a switched wire to #87. I find the relay is isolated so no voltage other then terminal #87. I assume the only issue is that I am back feeding my switch when the back up lights are on, but too is on a relay so I haven't seen any issues. Is there anything I need to be concerned about?

    I think you should have connected 30 to your aux/backup lamp(s). 87A to the positive wire for normal reverse lights. 87 to B+. And a switch as shown in this video. Caveat: make sure your aux lamps do not exceed the capacity of factory reverse light circuit.

    Sorry I don't think you explained the operation of a relay at all. I think what would have been better was to provide a schematic of what goes on IN THE RELAY. What happens before and after is simple. How it get there is what happens in the relay. All is seems to me is you are showing two lines with power going to difference places - not explaining how that happens.
