Headlight and instrument light switch question
I'm starting to plan my wiring harness installation, I just ordered a complete Ron Francis harness for my Contemporary. I have the complete car disassembled, the old harness is out, and the instrument panel is completely disassembled. My question is on the original controls for the headlights and instrument lights. What type of switch was used to turn on the head and tail lights? Was it a typical push pull light switch or a toggle switch? Anyone have the part number and supplier? Also, the instrument panel lights probably went on and off with this switch. I understand there was a rotary rheostat that was separate from the light switch that controlled the dim - bright feature of the instrument lights? Again, anyone have a part number and supplier for this switch? I need the small indicator lights for the panel (charge, directional, high beam). Does anyone know a part number and supplier for these? I would like high quality ones and as close to original as possible. Lastly, can someone provide a link here to a good representation of the layout of the S/C panel, with what the switches looked like and the position of all switches, indicator lights and gauges on the panel? Thanks.

You can get all your switches from here: http://www.holden.co.uk/
They do mail-order to anywhere. Paul |
Thanks, now if I only knew which switches they are!:LOL:

switches
Doug: The layout is in the build manual. If not clear enough you can take pics of mine. Also, Cobra Restorers or Finnishline have replacement Lucas switches and indicator lights. I just replaced 2 switches (outer pusher fans and dash lights). Call me.

Ralph - thanks! Please PM me your phone number.

The headlights are a double switch Lucas toggle 31807E 4388 I think as its small print. (Fuel pump and fan are both single switch 318280 2681.) The instrument panel dimmer is a rheostat with knob #3R 78405, also Lucas. (Wiper is also a knob type # switch PRS7 54033632) Horn? Indicator lights are metal, I think FL offers plastic MG type?

Were the original dash switches the 12.5mm or 14.5mm variety (hole diameter) and did they use the round ring retainers or hex nut? Thanks, |
Are you rewiring everything from scratch and not reusing any of the old harness?

Holden Nrs are:
-Toggle switch, Off-On-On,(Lighting): #31788 -Turn switch, Rheostat (Panel lights): #78405 -Knob, fluted for Rheostat, without writing: #316163, too expensive, buy knob at superformance dealer or cobrarestorers.com -Horn, push button, often used as starter button: #SPB106 -absolutely necessary for the correct switch look would be the turn switch for wipers with the same style fluted knob as the panel light one with correct writing on it. -> see again cobrarestores.com You can't be shure that the showed bezels (round or hex ) come with the toggle switches. Bought the same switch two times, delivered one with hex bezel and one with round bezel. The air knob on the left is fake, it is sitting on a alfa romeo pull switch with the correct chrome bezel switching a small axial fan for footwell ventilation.... Sorry for that red hazard warning switch, we have to use them here in Germany....:mad: Uwe:cool: |
Toggle w/ relays
Jim,
I used the 3-position Lucas toggle switch that is sold as a wiper switch for my headlight switch. To be safe, I ran the system with a couple relays so high amperage wasn't being switched by the switch. The Haywire harness is useable, you're just changing their switch for another switch and a couple relays. Recognize when you give up the Hurricane light switch, you'll need to do something for the panel light dimmer. I built one from RadioShack parts. After a number of builds, I then learned you can buy most of the parts you're looking for, including the dimmer and knobs, from Superformance for very reasonable prices. Paul |
