Aftermarket multiplex wiring parts
Aftermarket multiplex wiring parts
(OP)
I have searched all over and can't find any kits,etc. to wire up a complete car with multiplexing. Since I am starting from scratch, it seems like an interesting project to reduce the wiring complexety. I saw an article on a kit "super car" a year ago or so that supposidely came with such a wiring system, but I wasn't able to track down his source.
I am not sure of the cost justification compared to standard switches, relays, etc., but the lure of only one power line running around the car is pulling me.

Anyhow, Peugeot recently has used this tech and all 206, 306 and 307 (at least) have that technology. it reduces the wiring lenght but adds the complexity so much. Most of the tasks of sync-ing and stuff is with a unit named BSI in Peugeot.
As an example, you don't have a seperate wiring to water temp sensor to : a) instrument to show it b) ECU to adjust the injection c) to the fans to control their speed. Instead a single pair of wires go to BSI and then this unit sends required info to ECU, INST Control Unit and Fan Control Unit with already existing VAN (and/or CAN) network.
So, my conclusion is that sensors shouldn't be different as you need a SET of Control Units can talk on MUX protocol.
If u r making a new car, I would recommend NOT to use it and put your effort on other stuff like Engine and So on, Unless you wanna use a full MUX package with its associated Engine!
Cheers
You can live in your car, but you can't drive your House!

BTW, I am a retired Automotive Engineer (Ford) with a good understanding of conventional electrical wiring and just a basic understanding of how multiplexing works.
