Super Saftey Wiring Harness

PostPost by: mdf » Tue Feb 25, 2020 11:57 pm

I have a 67 Elan Super Safety which I am restoring. I have decided to replace the wiring harness - but I am not sure how to proceed. The people at British Wiring aren't sure if this car requires a S4 harness or a S3 harness.

It is a S3 - but it has a S4 dash board. Anyone know the answer to this question. What I am dreading is the possibility that the SS has a unique wiring loom.

Any input appreciated.

Thanks

Michael,
I also have an SS elan. I originally ordered an S4 wiring harness thinking it would work.....not. This was done about 10 years ago now. Working with the original S1, S2 wiring diagram and with British Wiring, we came to the conclusion that the S2 wiring harness would do the trick. Difference on the S4 harness was spade connectors where there should have been bullets, alternator wire instead of generator. If I remember correctly, the brake fail switch and warning light needed a wire added to the S2 harness and also a warning flasher needed to be added. So I purchased some wire to match the existing wiring and just wrapped the new wires into the new harness as needed(bought harness tape from B.W. ). Also window switches to door motors have small separate harnesses. You may want to review the additions to your car for the SS modifications and compare them to the S2, S3 wiring diagram. Buy a crimp tool, bullet kit and replace all the old connectors. Check your fuse block for connectivity and tightness of rivets in the spades. Confirm your voltage regulator is working correctly, otherwise poor connections especially with the main power supply will cause charging problems....took me years to find this out. While you are under the dash, replace the headlamp relay as cheap insurance since it's so hard to get to. I ordered a POWER PROBE https://www.amazon.com/Power-Probe-III- ... 335&sr=1-2 to test everything as you can connect to the battery and either ground or power a circuit via the probe. Use an inline short detector

like the round barrel one or similar. These have a bimetallic breaker which resets itself almost immediately thus no damage to any electrical.
PM me if you have more questions and I will try to help.

I also have a Super Safety and have pondered the same rewiring question. I had thought the decision would be between an S3 and S4 harness, not S1 and S2? I also thought things would line up better with an S4 harness but as Greg states, I guess the difference in connectors would be a problem.

I'll agree w/ Greg and Christo. I have three essentially S3 Elans, the eldest a 55xx pre-airflow FHC and the latest, an SS DHC. My garage copy wiring schematic is for an S2, both here in Florida and my shop in Ohio.

You do need individual wiring for the door window circuits and another loop for the brake fail micro-switch, but the rest is all Ser 2.
