GS550 wiring harness interchange? *edited* And RH control

[Scott S]

Trying to cross reference the part #'s. I have a 1980 GS550E/T. The part number I find for a wiring harness is 36610-47210. When I look up "where used", it shows the GS550L. Will the main wiring harness between the E (or T...I'm still a little confused about the proper designation), and the L model interchange?

Also, there is only one part # for the RH control/throttle housing. Part #57100-47500 supersedes all previous numbers.
But when I look at the controls on eBay, the ones that the list says interchange, they have different plugs. I'm not worried about the dual vs. single throttle cable.

How can I get a main harness and RH plug that will work together on my '80? The main harness is fubar...or too much of a headache to try and repair...and someone opened up the RH control and has lost some of the hardware. It's easier and cheaper to just find replacements. But the parts fiche has me confused.

I also found part #36610-47001

This is used on these models:

• 1977 GS550 - WIRING HARNESS
• 1977 GS550E - WIRING HARNESS
• 1978 GS550 - WIRING HARNESS
• 1978 GS550E - WIRING HARNESS
• 1979 GS550 - WIRING HARNESS
• 1979 GS550E - WIRING HARNESS

Can anyone tell me if the main harness is interchangeable and what will work on my '80? Just the main harness.

The harness part number seems to be P/N 36610-47020. I don't see any supersession listed. The 1980 bikes got electronic ignition and a combined R/R. Earlier bikes had points and a regulator and rectifier among other differences. There may be other changes too, not sure. With enough work I'm sure you could adapt the early harness for your bike. I've done such swaps before and they are doable.

Regarding the hand control, it's nothing but two wires so regardless of the connector you should be able to swap things around.

Part numbers...
Part# 57100-47500

*supersedes 57100-47010, 57100-47011, 57100-44130

Did some more searching, looked at a BUNCH of listings on eBay, found a nice used harness and a RH control. I'm 99% sure I got the right thing(s). And only about $36 shipped for both. WAYYYY better than trying to sort out the mess I have!

Will the main wiring harness between the E (or T...I'm still a little confused about the proper designation), and the L model interchange?

Generally speaking, the E and L harnesses might be a bit different, but the differences might also be in the sub-harnesses that plug into the main harness, I'm not sure.

As to "proper designation", you need to know that the "T" is Suzuki's designation for the 1980 model year. Therefore, you have a 1980 GS550E or you have a GS550ET, but saying you have a 1980 GS550ET is redundant. You can see the other years and their designations by looking at the GSR home page and scrolling down to the model information tab.
