Guys, before I ask my quite detailed questions - I have the utmost respect for the quality and level of knowledge in this forum as well as the dedication many of you show by answering to questions such as mine. Thank you from all of us beginners/occasional wrenchers!!!

So, here it goes. I bought a running mk3 roadster a few years ago and adjusted many things to my liking, including the latest winter project, Wayne's eight stack EFI intake (very cool parts) with the redline engine management system. It goes onto a barely broken in 5.0 engine with the classic GT40 aluminum heads setup and replaces the also common cobra intake paired with a not so common powerdyne supercharger (awfully period-incorrect, albeit working well, whole setup up for sale, just PM me). So far, so good.

Wayne does these swaps all the time and is very experienced, unfortunately I am in Germany and my local US car specialist has no issues with the mechanical side when we we put in on together, but the electrics...!!! Oh my, we took out most of the original Ford harness including its ECU connected relays, etc. I found only moderate quality diagrams for that original harness and there is no diagram coming with the Redline system. Only a pinout description.

Has anyone ever written a true instruction on how to swap the old ford harness and install the new redline harness? We are struggling with such minor details as the pigtail connector from the existing accel distributor only having five of six wires (seemingly there is a black and a grey version with different wiring), and other fun things like that, such as does the green/white redline tach-labelled wire go into the rpm-thing (sorry! German problem) or speedometer (which is called tachometer in German, hence the confusion), or even directly linked to the gearbox wires that ran into the ECU?

Again, Wayne can probably hook everything up blindfolded and half-asleep and I would give much to be able to have him look at it. But the car is in Germany and I happen to live in Switzerland, only visiting the car to finish the project before summer ends!

Can anybody help? Has anybody done this swap for a similar or even same setup before? Redline is no help, there isn't even a human one can connect to over the phone. And I can only hold up Wayne so much over the phone (thank you for all your help so far, if you read this!).

Help, please...?

All the best, Joe

i haven't done a swap but installed my stacks with a redline...I would just remove all the ford ecu connections and then hook up the redline with new wires...get it to run and then remove all the old ecu stuff...no need to try and get the ford harness to drive the redline....be sure your coil is ballast resisted or you'll likely smoke a driver on the RL..... there is a good set of instructions on the redline site...their relay block is worth the dollars too...where iv Switzerland?...I frequent Locarno and Zurich

Hi Quicksand,

I live in Zurich but the car is unfortunately in Mannheim, Germany at this point. Thats where my car mechanic friend is. Meeting you would be great! Always fantastic to meet fellow enthusiasts, especially knowledgeable ones :) Would you mind sending me a PM to the link at their website and to exchange actual emails to connect in reality? I looked all over for anything useful on that Redline site, but maybe I am just looking wrong (or am not smart enough from a car electric point of view).

Picking up on your comment - we did pull the whole Ford harness and are in the process of adding the new Redline harness to the car and hooking it up. But we have the TFI pigtail slight confusion, we have a whole set of accessories like lights and the dash components that somehow need to be also connected to, and the old ford harness had (seemingly) lots more connections than the new Redline harness. Also, we have a current catalyst setup after shorty headers with one O2 sensor on each side (need it to pass German emissions). The Redline ECU has a pinout for two sensors, but is only wired for one right now. The old wiring is quite a mess and we tried to clean out everything we could, but connecting the new harness is quite something.

On top of everything, I finally reached Redline today and spoke to someone by the name of Tom, who I wouldn't have called exactly friendly, after explaining that I had only ever reached a voicemail and had no reply to my help email to them and asking if I could directly call the referenced colleague, he replied no and hung up. I do not share the positive Redline experience/service I have read in some of the posts...? All I was asking for quite friendly is an actual installation manual (not just for the software, but the actual wiring).

Anyway, it is what it is and now I appreciate any help you or anyone can provide me with. Thanks a million in advance,

Joe (Jochen)

Just for everyone's info, I reached Bud at Redline and he was incredibly helpful. I will try to post a wiring diagram and pictures once all is done, so everyone can benefit from my research as well. Of course the outcome will be specific to the coil and distributor combo.

Thank you so much already, Bud!
