Signal flasher upgrade easy to do & what a difference

[Russell74Fjord]

+ 1 on all this, I used the EL13,, altho I did short circuit one in the attempt, so my additional advice is to buy 2 when you go to NAPA, inexpensive even if you don't need it, throw the extra in the glove box.

For those who have done this conversion, does the green indicator light in the dash still work?

[zinz]

Yes.

Followed this procedure closely and when I hooked the battery back up the horn came on!  What could I have done wrong?

Did you have a friend help you?

You might not have the plastic piece that fits into slots in the upper & lower steering covers in proper position.

Haha.  I don't think my repair shop has the time for elaborate jokes.  Upper and lower steering covers?  Where can I find a diagram?

Does the electronic flasher click too?

I'm not sure what joke you're referring to.  It's the part with the copper contact ring that stands up between the upper & lower plastic housing halves, as seen in this article linked below.  It & the steering wheel need to be positioned properly:

John, Rob was referring to the joke 76mintgrun posted.

 

Yeah the horn contact button must be precisely aligned to not get stuck on.

The problem may be that I can't identify which is the horn relay versus the flasher relay. See photos. I attempted to replace the relay on the fender not under the dash.  This might explain why the horn went off when hooked up the power wire up to the new relay.  

 

1. Can anyone send me a picture identifying the flasher relay and its location?

2.  What is the best service manual with diagrams?

 

Thanks.

The horn relay is the one above the battery and the flasher the one under the dash on the LHD side.

Update.  Followed procedure and external turn signals working, audible clicking in dash now works, but now instrument panel turn signal light went from one flash to no flashes.  Only choice is to hook original relay back up and see if dash light flashes again.

Rob, it never worked for me either.

 

You can grab a pair of diodes and some terminals and run power directly from available spade connectors on the 2 turn signal fuses at the fuse box, to the pigtail of diodes and then ro the black/white lead to the dash indicator. You don't need to cut that lead. Take a pick and coerce it out of the relay plug.

 

Kudos to Mike Smith for this.
