TTG foglight and under bumper fogllight wiring

[tgittens]

I'm installing TN4 TTG foglights and the under the bumper foglights on a 1969 911 and wondering if they can be wired together or does each need to be on it's own circuit with it's own switch?

As you may know, when both driving and fog lights were installed, they had separate switches. Fog by the cigar lighter and the TTG beneath the speedometer with a miniature bosch switch. If you don't have the miniature switch or you don't want to install a second switch, you could put the driving lights on the hi beam circuit with a relay and the fogs independent with its own switch. I would not want to be in line of those hi-beams

Olin, sounds like he is using two pair of fogs. One TTG and one under bumper.

You could run both of them off one main circuit/switch. I'd use the switch to activate the relay coil only and have the light current through the relay contacts. I would recommend beefing up the supply wiring to the relay, and the output of the relay to the fuse panel and then parallel to your two sets of lights through two separately fused circuits. The fused output circuits to your two pairs of lights could then remain standard wiring.
