Sure it is, take it out the front of the hole. You need a tool that catches those notices, or rubber grips to undo the bezel. Or am I thinking the ignition switch?

Nor so on a 72, which is why I haven't installed it yet. But I have some heat/ac control issues to deal with, an occasional loose ground somewhere that affects the instruments, and plan to switch out all my dash lights to LED', a project

I did purchase and install his intermittent wiper switch mod which turned out very well.

Re: Install daytime running lights on '67 Chevelle?

All the factory does to get DRLs is run the high beams in series. Instead of each filament having 12v and ground, they share connections through relays, one lead of one bulb will have 12v, the other lead will be tied to the other bulb lead, then the last unused lead goes to ground. Both high beam bulbs are sharing 12v, so each bulb will get 6v. That's why they look yellow.

(headlight bulbs are non-directional, so there is no polarity (+ or -), you can hook them up however you choose without messing the bulb up.


............Driver......................Passenger. ....................
12v---- +bulb- ----gnd 12v---- +bulb- ----gnd


............Driver...........Passenger............ .....................
12v----- +bulb- ------- +bulb- ------gnd

You can wire the bulbs up with jumper wires and test it out to see if you like the look before you commit.

I know it's pretty confusing, but hope this helps?
