Why go back to the dimmer switch for the relay trigger though. Trigger them from one of the existing headlight plugs. Like Frank said if something happens with the relays, simply plug the headlamps back into the stock headlight plugs. You will then have your old dim lights back.
???? Didn't say go back to the dimmer switch...the trigger wire is coming from the dimmer switch to the relays. If something happens to the relay...unplug the relay and connect a jumper wire with a spade connector on each end between the #86 and #87 sockets.
I'm missing what you're saying . Yes, the trigger wires (#86) power comes from the Beam Selector Switch, this is small amp power to pull the relay closed. The BIG amp power (#30) to light up the headlights comes from the battery and it will pass through the relay (#87) to the headlights after it is pulled close from the trigger wire's signal. The relays are mounted close to the headlights. :Handshake
I am well aware of how it works. The drawing you posted indicates that the trigger wires should be run to the beam selector switch. I am saying you can simply connect the trigger wires with a spade terminal to the old unused headlight plug. (which come from the beam selector switch) Since the relays are mounted by the headlights you can run 18 inches of wire rather than 9 feet. This is probably what you meant but the drawing doesn't indicate that. Just trying to simplify the installation for the not so savvy.
I see what you're talking about now. You confused me with "the going to the beam selector." The trigger wire electricity is coming from the beam selector...not going to the beam selector. It is going to the relay . I cut the wires going to the headlights and put in the relays. I have heaver 10 gauge wires from the relay to the headlights (less voltage drop). The idea wiring of electricity is to eliminate as many connections as possible. One could use the headlight plug for simplicity but the spade connectors would eventually start to corrode and oxidate over time. :Handshake Anyone looking into doing the modification...You can buy a 2 bank relay kit from Painless for $164 or you can get a 2 bank relay from a late 80's early 90's Dodge Caravan with a rack to hang the relays at the junkyard for $5 or $10. Be sure to get as much wiring harness as you can
Also Gen II S-10/Blazers have a realy nice set of weatherproof (Metri-pak) relays mounted high on the firewall just under the hood, really easy to grab and $10.00 or so (you'll get 4 plus a bracket). Russ
This 5 rack relay is also from a Caravan that I have on my Falcon. 2 go to the fans, 1 to the water pump, 2 to the headlights. The picture above has another 2 bank rack that interlocks with it
You're welcome Jay. I missed the post where you said you was gonna do an artical. Go ahead and copy/paste/edit
Talk to Jeremy this afternoon will be using his 72 mav for the tech artical ( no engine in it ) for some pic . Will have to wait untill after Knott's and Show an GO on the frist weekend of May . Stay Toon more Later Jay
