Stock wiring harness T junctions
« on: February 20, 2015, 06:16:10 AM »
I replaced some burnt ground wires when I got my '75 750 and it's been reliable since then.  Now with fresh paint on the frame I'm checking the whole harness on a bench and it's in very good condition.

I am curious about the T junctions.  There are 8 or 10 in the harness in addition to the multi-bullet connectors.  I would expect Honda to use crimp connectors for all T junctions.  What I find are very clean, workmanlike soldered junctions wrapped in thin and narrow gray electrical tape.  Is this stock?  While the soldering is very nice, the tape is wrapped so generously that it makes a pretty big lump.

Can anyone tell me what type of connection Honda used to make T junctions in the wiring harness?

Thanks.

Doesn't sound stock to me.  Here's a link that may be helpful:

I'm pretty sure my stock harness has some soldered splices.

That is stock.  On most harnesses I've disassembled, the tape wrapping wasn't overly thick.  Probably depends on which assembly line worker was doing the job.

thank you for that harness repair document that will be very useful... They always want you to replace the whole harness should something be buggered up. This allows you to fix the damage rather than replace!

OK then I agree too.  I thought the reference was to the multi-wire connectors.

Agreed, if we're discussing the soldered splices then they are that way from the factory. If we're talking about the multi-plug 3.5mm bullet connectors then you can get what you need at http://www.vintageconnections.com/

T junctions.  There are 8 or 10 in the harness in addition to the multi-bullet connectors.
