fog light wiring - blowing fuses

[bajaroadster]

C.Costine, Yes. I have installed them on the car and they look great. Even my wife, who indulges my love of roadsters but really doesn't pay much attention to the car, stopped and commented that they were a vast improvement cosmetically over the old fog lights. The look very period correct and really set off the grill area of the car.

Here are the wires that all the 66-70 roadsters have for the fog lights next to the headlight plugs. Red/green stripe for power and black for ground. This is a 67 2000 harness.

I have a similar set, I like the look and think they fit well and look period correct for the Roadster.

They look great!!

fog light relay.jpg

Installed my new fog lights on the car some time ago but just now getting ready to wire them in using a relay as described in the wiki tech section. The diagram shows the switch with three leads. Power in , power out, and a ground. I just removed the original equipment toggle switch from the dash (67 1/2 1600) and it only has two blades. Im assuming they are for power in and out as both of the wires connected to them were red with a black (possibly dark green ) stripe. Is the switch self grounding? Also, which blade to I connect to the fuse block and which blade to the relay

You can use your two pole switch. I think the ground in that drawing is so the switch is grounded and the light works. So the ground is for the switch itself and not needed if you do not have a lighted switch. The fog lights ground through the mounting to the apron, or if your lights have a separate ground wire, you will need to ground that somewhere (I suggest to someplace unseen on the frame). Original fog lights were single, power only wire. Replacement aftermarket will likely have a power and a ground. You will want to install on the "down river" side of the fuse, so if the fuse blows you will protect the fog light circuit.

Also, the diagram shows terminal 85 on the relay as the power terminal and 86 as the ground. Is that correct? I only ask because I watched a tutorial on U-tube and it said just the opposite !? Heres a screenshot from that video. Electrical is my absolute least favorite thing to tinker with as I have no experience but ya gotta learn sometime.

[Curtis]

The relay doesn't care which one is ground, 85 or 86.

Thanks Curtis, I thought that might be the case but i'm not taking ANY chances with electrical without some advice. Is it safe to assume that the toggle switch is the same with the only difference being which toggle position is off and which is on? Or does the power supply to the toggle have to be to a specific blade?

[Curtis]

Power should go to pin 6 and out to pin 7 on the toggle switch.

[bajaroadster]

Curtis. A quick check of the switch shows no marking or stamps. Is that a reference to a wiki wiring schematic?

Numbers are next to the terminals.

I made a switch layout drawing for all the toggle switches last night. You'll notice that the wiper switch is turned 180 degrees.

Added some labels and corrected a couple things.

Well, now im really confused. (full disclosure, that's a pretty common state of mind for me.) The pic that Curtis posted looks nothing like the toggle switch I removed from my dash.I haven't removed the cover from the switch and am reluctant to do so on a 50 year old toggle switch, but im not sure we are looking at the same thing. After cleaning up the switch a bit , I did discover some stamping on the prongs and the cover. (see pics) The prongs are labled 1 and 2 but that's about it. Please continue to be patient with my incredible mechanical ignorance. We got people here doing engine swaps and major fabrication and I gotta ask questions about toggle switches. Its a bit embarrassing but the nearest qualified Datsun mechanic is about 800 miles away. Ill just keep plugging away. (No pun intended)
