Single Pole DT, here is their description on Amazon. Yes switch cuts light on and off, when I introduce 12v+ to the green terminal on the motor it cycles.

Yes, that's exactly how it's wired now but the door opens and stays open, light works fine and I hear the relay engaging. Do you want me to switch the wires?

I finished the wiring job. When I powered up the relay the first time, the door opened and locked open, does that mean I have to reverse the green and green white wires? Thanks for all the help!

OK, I'm going to try your setup with 87a relay it seems simpler to me. I'll post again soon after I have the test wiring setup working - thanks again for your help!

Yes, two for the coil at the bottom and six contacts above it, one pair N.O., one pair N.C.,and 12v fed to top contacts. $12 for a pair of 'em with base disconnects in case it fails. And yes it is a 12v relay.

Here is my drawing of proposed wiring for Cyclops, 8 pole DPDT relay and original switch. I made one mistake in the drawing, Black/red and Green/red wires in the harness are looped together. Please check over and let me know if all is correct. Thanks a lot!

Look at Chris' links near the top of this thread, there are two schematics and instructions for using the DPDT relay. Luckily I have a bench top 12v power supply to test everything before it is installed in my Brat. Will share my experiences as I go!

Thanks for your help, again! As I wrote earlier in this thread, I have both types of relays. According to Chris' DPDT Relay plan, he calls for the use of an 8-pole relay. I purchased two and they are very easy to source. For clarity's sake, I'm going to draw a schematic of my own, which follows the 8-pole DPDT Relay, the original wiring harness and the original "Center Lamp" switch. This way hopefully everything will be laid out for other folks to follow if, like me, they have the switch and the cyclops light but are missing the original factory relay PCB. UPDATE: A friend offered to send me his original 82 Cyclops Front Grille! So as the job progresses I will upload photos and I hope this helps the group!

Chris, I just got the 8 pole relay and everything I need to start the hookup. I'm confused about three of the wires in the harness coming out of the cyclops, see attached and thanks!

I saw those schematics, thanks! I could actually go either way being that I have both kinds of relays, but it seems to me the easiest way is with Chris' plan which seems like the easiest wiring job. Also it appears with his the cyclops can be used with either high or low beams, no need for a second auxiliary switch. Since I have an 83 Brat GL with four headlamps, I pity the poor driver in the opposite lane when the highs and cyclops are on together, lol!

Thanks a lot for that info! BTW, I'm planning to use 18ga stranded hookup wire for this job, just got a special automotive crimping tool to get it heatshrinked together. I'll take some pics and post when it's finished up.

Update I ordered an 8-pole dpdt relay like the one you pictured. Also just tested my unit with bench top dc power supply. Both the motor, acuator arm and even the original light work! I noticed the motor runs continually and assume the relay will tell it to cycle when the switch calls for power, raising the door, and when I power it off with the switch, that the motor will cycle to close the door. Really excited with the progress and thanks for the help!

What do you want for the original honeycomb grill with shipping to 10301? Thanks! I should mention I have the original untouched slatted grill, see attached of original 82 grille designed for cyclops (pic is upside down, lol).

Thanks for your help! I got a set of 87a relays from Amazon that are five pole can I use those or do you want me to get this relay? If so what is the part and where can I get one? I would rather use the "Center Light" original switch if I can rather than a dpdt switch.

No I want to keep the four headlight GL style.

Just got a working cyclops 3rd eye setup for my 83 Brat GL. Have the original switch, but missing the original relay pcb. Also don't have the original 82 grille that matches the cyclops. Purchased a set of 87a relays and have read posts here how to wire these up using the original switch. Can someone please reply with a working, known to be good spec for getting this setup working? Also would be very interested in purchasing an original cyclops front grille. Thanks!
