Just bought 2 EF32RL electronic flashers at amazon. Which is the neatest and safest way of installing the one for the turn signal lights and the one for the hazard switch? Both of the flashers have 2 prongs and one black wire. Please advise.

 

Any pictures?

Just ground the black wires. That wire serves to complete the electronic circuit that does the timing.

Any pictures of a neat job for both flashers? One under the steering column and one under the passengers glove box (Hazard switch relay)

Sorry, all I cared about was sound operation. No beauty pics.

What about grounding the black wire to a bolt in the steering Wheel?? I found out the former owner threw a wire from the negative pole of the battery through the firewall and tied it up with electrical tape to the black wire of the electronic flasher relay. I dont think there was a need to do that when you could ground at the bolt of the steering Wheel. Anyone has a different view?

I grounded mine to the body as you describe.

I still dont know what was the former owner thinking on throwing a 16 GA cable from the negative pole through the firewall and patching the cable with electric tape when it was closer and easier to ground it to a bolt in the steering column!

You have 40+ years of amateur mechanics working on your car adding, deleting, or replacing things. If this is the only head scratcher you find, you are doing much better than average.

thanks!!!!

Which module was used for the hazard flasher, and would it work for the 1978?

It's obviously a case where the PO  didn't think there was a closed path between the battery and the interior or the car.  I recently added a nice braided ground strap to my engine.

Hi all, I have a 75 260 Aust spec Z car and have just installed a US hazard switch as our cars came with wiring but no switch. The problem I have is that when activated only the right hand side signals work not both. Any Ideas why this could be happening?
