Interest in EHC bypass kit?

The EHC on my bike fried yesterday. I figured out a way using some relays, a switch, and the existing harness, to get my bike up and running again. I'm thinking about designing a kit that eliminates the EHC, uses existing wiring (so that all factory switches, etc.. work as usual) and involves some cutting, soldering, heatshrink wrap, as well as some weatherpack connectors.

I'm gauging interest to see if those of us who are "electrically inclined" would like for me to design a bypass kit using the factory switches and most of the factory wiring. The kit would range between $150-300 depending on parts used. The best part is that you would not need to re-wire the entire bike. :whoop:

Question for people that have had the EHC go bad: What trouble lights appeared on your EHC and what what were your symptoms?

I tried to go that route a little over 2 years ago before working with Wire-Plus to design the module to make the hand controls work.


You could design such change over kit and do it for $300, BUT there is not enough room in our bikes for a bank of 6-8 relays, flasher, auto turn cancel module, all the wiring...

...and besides all that added stuff wont be any more reliable than the stock EHC with the vibration in these bikes. :2thumbs:

Just trying to save you alot of time that I already wasted trying to do just that. :cheers:

What you're talking about has already been done with the wire plus. There really isn't any other way to do it without changing out the bars and switches. I did run my 2004 Chopper for a season with the ignition and headlight bypassed through switches under the seat because pretty much all my EHC functions had failed except my brake light. It's a simple task but a half assed solution in my opinion.

If that were true wire-plus and BDM wouldn't have been able to do it. It is just signal detection, not a big deal. The problem I have with wire-plus is they have no more than $50 in parts and $50 engineering per unit and they still charge $520. It's because they have no competion that they get away with it. The other problem I have wire-plus is having to cut wire harness, I like keeping things factory. Why didn't they make it with modular connectors to single or dual BDM connectors?*
I was a electronic tech for 20 years before changing to programmer. I would like to find out cause of EHC failures, processor or other part failure, so if any one has a defective EHC that is willing to part with it please send me a PM. EHC needs to be one that was encased in clear resin.

Might want to toss up an Intro so we know more about you and we can give you a proper welcome.

I am very interested in the WP but cannot swing the price right now, so I for one would be seriously interested in seeing what you come up with. I gotta think there are many more with the same thoughts on this:2thumbs:

:iagree:You've summed it up in a nutshell!!!

Although, after doing some shopping at Digi-Key, I do think there's may be little more than $50 in parts but certainly nowhere near the price charged by WP...

So, your saying that you want to keep that computer serial plug that BDM shouldn't have used on the EHC in the first place?

The Wire-Plus kit has $50 worth of Deutsch connectors alone to make it.

No competition (If you call it that), Thunderheart makes a kit as well to eliminate the EHC but you loose bike features, and Thunderheart already proved that they couldn't build a EHC back in the early parts of 2000 that BDM used.

The thing is, Wire-Plus makes a part that works, has NO problems what so ever, and it replaces a $550 EHC that is 1/2 the quality.

Im with Jake, It works and the price is reasonable ! these are not $2 bikes. Its not just the parts ur paying for its the pass on of knowledge.......

interested in what you come up with. more options make it a buyers market.

still have the original EHC but an aftermarket ignition so i cant comment on any symptoms.

a $2 bike??????

What does the serial port have to do with anything?:confused: It didn't cause the failure. I would still like to get my hands on a couple of defective EHC's, I still want to see if failue is processor or other parts. Solid state is still more reliable and can be made smaller. One of my biggest worries is sourcing connector A.
As far as thunderheart as a replacement if you lose features then it's not an adequate replacement.
I think Wire-Plus is the best option at the moment:2thumbs: but wished it monitored the oil pressure switch so it would shut down engine if there was a loss of oil pressure, or even monitor the neutral switch so if bike was in gear it wouldn't engage starter.
I'm not saying I can make a replacement by myself but I could get pretty damn close and with help you just never know.
