Hi chuck,
I wrote that bar wiring article on Matt's site.
The problems I ran into were:
- No source for our wiring and had to go with an aftermarket company and different wires
- As Rob said, the control sides are soldered in and even though I have soldered for about 35 years, I did not want to disassemble the controls, de-solder, and re-solder
- The connector blocks pins and sockets were difficult to impossible to remove. I own almost every extractor tool made and none of them would get every one out. I looked in all my elctronic resource catalogs trying to find something close to no avail
The final decision to lengthen was made due to time and effort. Just too much of both to justify the work.
Good soldering and heat shrinking all joints have made my installation trouble free for well over a year now. Been through some extremely heavy rain too!
However, if you can find the proper extractor tool and your bars are shorter than stock, you might be able to get away with running your stock wires through the bars with no modification. Good luck to you!!
