help with 3.2l conversion wiring, have a PMS 3.2l to 914-4 conversion cable but... Options

[jim912928]

Well, I have all of the mechanical work done for my 3.2l motronic conversion. Now I'm trying to figure out the wiring. I purchased the Patrick MotorSports conversion harness a few years back. It allows me to eliminate the relay board. However, electrical is not my forte...so I have some real questions on the "trunk" wires from the 3.2l harness and what to do with them. The engine, dme and wiring harness are all from the same car. So, here are my questions and you can relate them to the pictures as shown:

1. picture named "DME help" circle #1: by the dme connector...there are two little stub connections that seem to come out of the DME connector and both wires are brown....do these need to go to anything?

2. picture named "Trunk help" circle #2: I marked these fuel pump...do I cap these because I'm using the 914 wiring or do I need to connect them somewhere?

3. picture named "Trunk help" circle #3: I marked this positive battery...does the 914 harness cover this or do I need to connect it to the battery also?

3. picture named "Trunk help" circle #4: green and green/yellow wire...have no clue what this is?

4. picture named "Trunk help" circle #5: black wire by the wires I labeled "fuel pump"...have no clue what this is?

5. picture named "Trunk help" circle #6: white connector with a black, black/purple and yellow wire...have no clue what this is?

I also would like to know where you usually mount the DME and where do you pass it through from the passenger compartment into the engine compartment..and once on the engine compartment side...where do you route it up to the engine? Have pics from those angles?

Thanks all in advance!

Jim

Jim,

There is an Tach up shift setup but I did not even consider finding it or connecting it. I did not find anything relating to it in the harness on the resistance path checks I did in matching the wiring harness (3.2 engine). I have you a package with the wiring schematic/diagram along with the 3.2 DME computer pin assignments. I also included the tach pin assignments which are as follows for the 3.2 Motronic engine:
Power to tach #5 pin on back - provided by the 914 wiring
Ground to tach #6 pin on back - provided by the 914 wiring
Engine harness black wire to #1 pin on back of tach - from DME pin #22
Engine harness black/violet wire to #2 pin on back of tach - from DME pin #11

Please use an ohm meter to verify the different paths on the engine wire connections in question, and note what they should connect to following the schematic/diagram. this information will provide you with the answers to where what goes where, etc.

Package will be in mail Monday

Mark, I am sending the same package to you with the same information.
