Here is a new relay board for the Porsche 914 - 4 cylinder. It is CNC machined from HDPE polymer plastic and all of the connections are soldered wires. The inside is sealed with epoxy preventing any moisture from causing corrosion. This relay board uses the stock relays for power, heater and fuel pump. There are no provisions for the rear window heater. The relay socket used for the window heater is used to store an extra relay.
This board uses an ATC style fuse and has an LED that illuminates when the relay board is supplying power to the fuel pump. This is useful in diagnosing fuel pump issues. The LED illuminates for about 2 seconds when the key is turned on and remains illuminated when the engine is running. This board does not come with any relays or the voltage regulator. Sorry, I can’t ship international. $325.00 Shipped.

A work of art. Why no rear window heater provision (just curious)?

@Steve_R

Nice work. Three observations

1. You made the relay sockets recessed. I doubt the 914 Rubber relays will fit that board as they are slightly larger is diameter.

2. The socket for the body harness has the female locating hole but not the male locating pin that the engine harness connector. I think the factory made both to reduce the possibility of plugging in the harness one pin off. I know if you do that on the engine harness it will fry the harness.

3. No holes for the voltage regulator. I do a thicker area on the side where the hole go. These need to be carefully drilled and the correct screw length used or the circuits will be damaged.

The shape of the relay "socket" would preclude using our relays. It is an interesting choice in that even the stock ones will be a tight fit.

I had looked at making the open source relay board that is available, but the machine cost was over $150 a board didn't see any margin as we have guys rebuilding these for less than $200.

Kudos to you for taking this on, but it's a lot of work and the details can be a big problem.

Thanks for the comments.

1. I have not tried the 914 Rubber relays. However, The stock relays sit on top of the boss so if the 914 Rubber relays are a little larger they should work.

2. I omitted the male locating pin and increased the distance from the female hole to the edge of the raised area. This will not allow the connector to be plugged in one pin off.

3. The pic in the post was before I drilled the holes for the voltage regulator. All of the relay boards have the pilot holes drilled and I supply the correct screws/washers.

Yep, it was a ton of work. I only have a few left and I will not be making any more.

How does one know when it's time (or almost time) for a new relay board? What are the symptoms and visual cues?

Things stop working. (IMG:style_emoticons/default/biggrin.gif)

Here's a link to a wiring diagram that shows everything that runs through the board.

@dknechtly

I think if my memory serves me correctly he is not planning on making any more but passed this along to Mark Whitesell and 914rubber @mikey914 might be able to chime in here i think they were going to pick this up and make them , if we had enough people that wanted this i bet he would do it.

Thanks. It's tiresome to deal with refurb'd parts only to come with the same issue in a year or two.

Agreed!, i was stranded last fall, for the first time in 12 years due to a failed / shorted out relay board!! that was the one part i didnt have a spare of in my car . Missed okteenerfest due to it. I am still looking for a NOS or one of the new ones he did that someone would part with to have as a back up but right now i have a nice refurbished one from 914sixer in the car, but no spare.

Wish mark would make these, i know he said it would cost $150 to make but i would pay $250 for a new one, i think many would too , it dont think its a close second to get a refurb for $150 or $200 if you can have a brand new one for $250.

Yes we have made some progress on these. The costing is where we are having the issues. You know me I try to keep it as affordable as possible. I'll post up some pics later today.
