The wiring continues, and I feel a bit better about it today. Fuel pump, ECU, relays seem to now be isolated and working, thanks to Dad.

As he was running different combinations, and trying to decode what was done to the wiring for the oil-cooler and fuel pump (it's a mix of multi-colored and spliced wires, romex, and Home Depot connectors), I parked in the Drivers seat for a couple of hours to try to see if I could work my way through the rats-nest.

Some before and after photos, as well as progress on component wiring...

Progress!

Trying to organize this so it makes sense, and then resemble a more stock-looking harness afterward.

Side-note: I recovered a few rubber pieces from the 75’ 914. Can anyone recommend a good method for cleaning and refurbishing? I’m thinking warm water with a bit of Simple Green, then a slow-dry, and maybe some ‘back to black’ to finish it off.

Simple green usually leaves a white residue.

Look at Griot's garage, their rubber cleaner works decently

"How do you eat an Elephant? ...One bite at a time"

Today was dedicated to get some sort of form on the wiring harness going from the fuse board to the dash. Most everything works, but we still need to integrate components of the 3.6 harness. It's not perfect, and not the final run, but this gives us some sort of an idea on how the harness will 'run'.

I haven't completely mounted everything, because I'm still accessing the switches, but it is MUCH more organized and pretty easy to work with. Most connections are labeled, but I still have a few orphans.

To make things easier for any future adds, I'm relocating the 12v 'junction point' that's below the dash to be more accessible just behind the gauge cluster, as well as adding another for Ground.

Plan is to finish up the wiring; verify, trouble-shoot and add everything. Then I'll address the harness one-more time before buttoning up the dash.

End-of-day, and we are testing! So far running lights, turn signals, headlights are a go. Current challenge is the pilot lights!

When routing wires over the steering column MAKE SURE you keep everything away from the U-joint. Terrible things happen if wires get snagged in that joint.
Ask me how i know.

Thanks for the heads up! Great advice for anyone reading. Though I haven't had that happen in a car, that has happened to me when wiring out Driving Simulators. Not a fun time.

Eventually, once everything is working, updated, and confirmed, I'll remove the zip-ties and either bind the wiring with fabric-tape (to look somewhat like stock) or safety sleeving. I prefer the safety sleeving, it's what we use on our sims and makes everything look cleaner.

If you have it, I would safety sleeve the wires after the fabric tape. Overkill? (IMG:style_emoticons/default/beerchug.gif)

Lol, I think you’re a gluten for punishment.

Question for the community here. We are mounting the 914/6 steering column, and notice a slight angle, maybe 2-5 degrees to the drivers side door. Is this normal? I have yet to see it with the dash pad and mount on.

[mb911]

Yes that is correct.. Been. Topic several times..

Looks like you are doing a bunch of stuff that I have already tackled on my conversion. I did the steering column and ignition switch years ago, and I am just finishing up a 964 based 4.0L install. I deleted the DME relay, and went with solid state bosch square relays.

Also, I noticed you have the /4 headlight relay installed. You won't need it with the /6 column.

Let me know if I can help.

Clay, thanks for the post! Please do-tell, and leave your response here should anyone in the future need any insight. We did find a few ‘funky’ things happening now that we are trying to include the 914/6 steering column, and you have me thinking about that relay.

Also, very excited to hear your thoughts on deleting the DME relay, my conversion is 964 based too.

Thanks in advance, eager to hear from you.

EDIT: Briefly looked over your project thread, really like what you did with the coils below the battery. Again, eager to hear your thoughts on the above!

The coils are mounted to a factory 914-6 CD box bracket. Makes for a place close to the distributor. I also put the FI grounds on the same post as the negative battery cable, and added a second ground cable to the engine at the right front corner. I wanted to insure a good ground.

I extended the DME harness so I could put the ECU on the front passenger wall. I cut out the foam block (fyi.. it is actually compressed and shellacked sawdust) to fit around it. I had to add a diagnostic plug, so I got a OBD2 plug kit off evilbay, and wired it according to the adapter diagram.

FYI.. 914-6 wiper switch has what looks like a plug for a relay on it. The other end attaches directly to the 914-6 wiper motor. The switch doesn't connect anywhere else, and the only wiring to the 914-6 motor is a single power wire.

If you are going to run anything other than LED bulbs in your headlights, you need to add a headlight relay kit to your wiring. The switch in the column takes the full load of the headlights, so the contacts burn out with any load more than a sealed beam or LED light. I don't want to sound like a shill, but this kit works good: http://www.allzim.com/store/zim-s-12v-brig...-relay-kit.html You will have to modify it slightly for a 914.

Let me know if you have any questions.

Well, back at it on-and-off, and the wiring is proving to be too much for me and my Dad, recently. I don't think it's that it is so difficult, but rather that it's hard to start-and-stop while remembering what work you accomplished in the last session.

Considering, currently, either going with a more modern, simple solution (suggestions welcome) or, taking the harness out of the car that had the 3.6 installed in it previously. I think this would make matters a lot easier, as everything is correctly 'loomed'. All I would have to do is 'adjust' and figure how to integrate the /6 steering column controls (wipers, etc.)

Eager to hear the groups thoughts!

I got nothing Rique just glad to see you back at it (IMG:style_emoticons/default/piratenanner.gif)

[Cairo94507]

RiqueMar- I second that. Glad to see you back and making progress on your project. (IMG:style_emoticons/default/beerchug.gif)

@RiqueMar (IMG:style_emoticons/default/cheer.gif) good to see you back at it
