Could someone check my plans for wiring the fuse block?

For anyone that has used one of the fuse taps, how did you get the wire down below the fuse box?

Hey Arth, the one I got from NAPA fit under the lid with room to spare.

I am going to put the relay/fuse block for the harness under the passenger foot well. I need that wire off of the fuse tap to go under the Porsche fuse box without breaking it's water tightness.

Just drill a small hole through one of the blank relay areas. Oh and I wouldn't recommend a fuse tap ever. It will only cause you problems down the road, Pull up the fuse block and find a good wire to get power from.

I am going to take it from the smaller of the two black and red wires behind the ignition switch. Thanks, for everyone's input.

Make sure to document exactly what you do for later reference. It is always a good idea to print out the page of the schematic [in your case the page that shows the ignition switch] and draw in the line you add.

The red/blk key-on wire from the keyswitch goes directly to the DRIVER"S side of fuse #36

I need to see which way is going to be easier to get to. On my back soldering in front of my face or while holding up the fuse box while trying to splice in a wire. Just in case anyone searches for this later, it is the smaller of the two black and red wires that you want.

Something else I have a question about. The DME gets a straight line of power directly from the battery. Since you won't be using the DME you could cut that wire and reuse it as constant power for the harness fuse box, right? It is too late for me, I already ran a new constant power wire. If that is correct it would make the wiring easier.

The easy way is that double fuse jumper that Spence posted. I've been running it for over 5,000 miles and ZERO problems.

has anything been conclued here ? im making my harness and was planing on getting my 12v switched from 14pin on my 86 944 ?

If you get rid of the dme relay, you can attach the old coil wires together (green and black by the passenger side headlight). This will let you use green wire in the 14 pin connector as 12v switched

On mot quite sure I understand which green wire I could use fo you have pictures? I was talking about a 12v switched at the 14pin connector

Where the old coil was. Attach the green and black wire together. This will then power the green wire in the 14 pin connector.

no pictures... Just go look at your car

so if i attache those wires i get a 12v switchs ( green ) at the 14 pin ? i will test it Thanks that is if i delete the DME Relay if i understood ? or you guys bypass it ? is it possible to put a normal relay in that position of the dme relay? or the hole is Porsche hacked?

Remove the DME relay and attach the old coil wires together and you will get 12v switched at the green wire at the 14 pin connector.

worked like a charm ! i would like to know if on pin 6-8 you guys have 7.5 volts and pin 9-10 a 12volts ? i dont have a 12v switch on the 14 pin connector for the fuel pump i find it weird or the pcm controls the 12 v so i dont have it ? im missing something lol\ ohhh wiring i dont play with it often enough

You will need to add in two relays. One for 12v switched and one for fuel pump (pin 4 blk/grn).

You've got alot of reading to do and all your answers are here if you read & search.
