Another detour - PCB design

So, looking at my very messy dash wiring, I'm wondering if I can really clean it up if I mount all the switches, relays and fuses on a printed circuit board. Anyone gone this route? I've seen the guts of a few sevens, and it ain't pretty behind the dash.

That would be kind of cool. But the variety of switch and instrument connectors don't really lend themselves to mounting on a PCB. With short pigtails I think it can be done but the layout work would be tricky and the manufacturing not cheap (given the size). Future modifications would be another problem.

 

But I think it is not really necessary. With a little attention it can be made pretty clean and maintenance friendly. This may preclude using the stock wiring loom, though......

 

The wiring as shown below was made using a Painless harness with mods.

Mazda,

 

Here's an idea.

These gadgets are similar to the high end power distribution modules used in real race cars. Still pricey, but 1/3 the cost of the offerings from Motec, Kronenberg, and Stack.

 

I'm not sure what data buss protocol the Cole Hersee units use. The 'spensive PDMs use a CAN buss.

Bob, that looks nice, but I don't see a price list for it.
