I've got some LED windshield nozzles that I would like to wire to the parking lights but I want to go through a toggle switch so I can turn them off. The wiring needs to go through the firewall to the switch. After drilling a hole through the wall, is there any type of grommet or rubber piece I can use for a clean looking passthrough? Also, once the connection is made from the nozzles, through the firewall, to the switch, can I tap into the parking light wire on the inside of the car or do I have to tap into it at the light and feed all the way back through the firewall too. It seems that I should be able to feed it from the big 'ol wire bundle inside. I just don't know which wire would be the parking lights!!

 

U dont have to drill a hole thru the firewall... There should be plenty of places to push the wire thru... But Id wire it to the corner light, to the switch, and then the washer nozzle, and the ground it out on the hood somewhere (should be a screw on the hood somewhere)...

 

If I understand you correctly, I would tap into the wires at the light - through the wall - to the switch. And from the nozzles - through the wall - and also to the switch. Power could be turned on an off to the nozzles as long as the parking lights were on I think.

I looked at the firewall but couldn't see an easy place to sneak the wires through. All of the spaces I see that wires go through are put through rubber grommets and that plastic stuff (wire loom I think it's called?). Any suggestions?

By the way, it's the '91 CRX firewall, not that I think it's changed much from the '90.

 

Look on the passenger's side down a little bit... Ill try and get a pic of it... But on mine theres plenty of room down there, and it comes out right behind the glove box, u have to get down on the floor of the car and look up behind it to get the wires...


But yea, I wired my g/fs LED washers like this:




Just instead of the driver's side, use the passenger's side... Ill try and get the pic of the place to go thru for the firewall...
