I need some help on where to hook up the yellow and gray wires for the 8969 window switch,ive tried searching but found nothing i would appreciate it if some one could help me out.

 

i hope someone helps you out im fixing to get the same switch.

where did you order from if you dont mind my askin?

 

i got mine from jegs i was in a hurry to get it and they were the only ones that had them in stock. i hope that helps if you want it quick they can get it to you with in a day.

 

Red hooks up to +12v switched, black to ground, yellow is normally open, which supplies ground when in the range. Hook the yellow wire up to the ground on the relay. I don't have a diagram on me, but I'm sure someone will post one. Also, do a search, there are lots of diagrams that have been posted before.

 

the gray wire is for nothing dont use that wire. the yellow one goes to one side of your fuel pressure safety switch if you are using it. if not, then the yellow connects to the ground wire coming off the relay for the kit. i hope this clears it up for you. if not then let me know and i will try to get you some diagrams. basically all u need to know is that the gray wire is for nothing and the yellow is what you will need. the yellow wire is your path to ground. when you set ur rpm at whatever ur going to set it at, it will turn on at that rpm if you use the yellow wire. if you use the gray wire it will shut off at 3800 or whatever and turn on at 5800 or whatever. use the yellow one. just hook it up in series with your ground coming off of your relay, fpss or not.

 

so by just using the yellow it will say turn on at 3000 and go off at 6000 still or do i need the gray to turn on and off at set points.thanks for the help

 

The gray one is for a normally closed circuit. Since you are using this for nitrous, you don't use the normally closed (gray wire).
