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

Has everyone got a basic understanding of what is happening regarding the wiring??

We have not touched on the oil pressure, oil temperature, vacuum gauge, etc. wiring. This should fall into place after you get use to what is going on with the changes thus far.

It has also be asked for my opinion regarding oil cooler, hoses, etc. Also, what I have done to my car. The way I am going to answer the question which I think is one of how to get the project started and completed to a running state. I did not want to get involved in this yet since there are still many practical questions to be answered. One of guys is planning on getting his conversion done some where around the first of the year. So the following is the way I am going to answer it with the express idea of building to running state.

Please, anyone chip in and add their comments especially in areas I may have left out or made wrong comments.

First, let us get away from the front oil cooler and what the needs/opinions are since it is not necessary to get the car running. Mark, I will send you more detailed information regarding additional items (including oil cooler, etc) after I finish this thread addition.

What is needed to get the engine in the car and running:

engine sheet metal
front engine mount
914-6 oil tank or equivalent
oil system hoses
rear transmission mounts
modified shift rod with new bush, pins, universal joint, etc.
KEP clutch package including ring
cut knotches in 901/915 transmission bell-housing
1984-86 ??? flywheel
throttle rod, yoke assembly
modified throttle engine yoke assembly (throw needs to be reversed, 911)
headers at least (no heat - separate problem which can be solved after engine
is running; electric heater, gas heater, heat exchangers, etc.)
electric connections being discussed in this thread
engine oil cooler with 90degree elbow modification (to clear left suspension)
exhaust muffler
installation of fuel pump, fuel filter, and lines

There may be more and please add to this check list freely so that we may get all present and future Sixer builders the information on sources and parts. I think all the parts can still be obtained either through Auto Atlanta, Pelican Parts, A914Guy, and others. A list can be developed but do not forget our own 914world, 914club manufacturers/suppliers.

I guess I have opened everything up for comments and additional information from everyone in order to assist our new "Sixers".

Now to comment on several areas including the front oil cooler.

Front Oil Cooler: is going to be somewhat expensive; you may need it in the summer time in North East, South East, Mid-west, and Southwest including Southern California; there are many opinions on this subject matter on many different boards and I will not make any comments because I do not know the answer; each has to determine for him/her self. With that comment made, the items needed will be hoses re routing the engine output side to the thermostat/bypass valve, one line returning from thermostat/bypass valve to the oil tank; one thermostat/bypass valve; two lines to/from front oil cooler; front oil cooler and mounting; shrouding; air inlet and outlet; fan system;etc.
As mentioned before it gets expensive quickly and it does not affect the problem of getting your engine installed and running. This system can be added later when you can concentrate on it entirely. Very similar to adding 911 e-brake, different CV joints, axles, bearings, stud shafts, etc.
There are some very good expertise on the subjects coming up later in the total car build; these sources are McMark, Sir Andy, Joe Sharpe, Rootwerks ???, A914Guy, Pelican, Auto Atlanta, our 914world and 914club boards, Brad Mayeur, Perry Kiehl in Tennessee, and many others. Even the "Great Doc Evil" is somewhat of a source. KEP (Kennedy out of Palmdale, CA). Cannot mention everyone but you get the general idea.

Again, who every wants to comment come-on aboard!!!!
