Wiring for early GTI system

[Golf Loon]

So I just got this engine from an early GLI cabrio and it has no wiring loom with it. It does not need an ECU and has minimal connections needed, was just hoping one of you guys can tell me how to hook it up.

May end up junking the full electronic system from the jetta and using this one.

Yeh, I used to make looms for K-jet.
Make sure that you get the correct fuel pump relay.

I`ve got a relay, do you wanna make me a loom?

I have a complete early K Jet loom from my Scirocco which I would swap for a good un butched LS or GLS loom.

[Golf Loon]

I`m up for that swop, I`ve got a few looms. I`ll check tomorrow how straight they are.

Although you have just reminded me that I should have an early Audi 80 loom, which is prob the same.

Loon why don't you run the Jetta on early no computer k jet like early mk2 GTIs.Mine is UK import with no ecu at all.Purrs like a kitten

[Golf Loon]

Yeah didn`t think of that till I got home with this motor, but its probably the shot, as its simple and the airbox is smaller.

It still needs a couple of wires though doesnt it?

I want to get her going by the weekend if possible for the cruise.

only electronic ignition.
Use early type fuel metering unit (Saab ones are a go) without the need for any electronic adjustment, and a simple vac adv type dist.

[Golf Loon]

Ive got the original cabrio metering system is that better than a saab one? And literally no other wires!!!

[Golfwise]

assuming the fuel system is already wired up.
Well I assumed it was

You'll need the k-jet fuel pump and plumbing too, it runs mote than twice the fuel pressure. I think the K-jet swirl pot (plastic box the fuel pump sits in) is different because the pump is bigger.

Now this could be the problem. At the mo, the car runs for 5 seconds and then dies. Could be fuel, or something electronic.

I have tried it with a commodore vl fuel pump and no inline fuel regulator, just the one next to the metering head and it has the above symptoms.

Then I tried the fuel pump and regulator from the early gti kjet system and it seemed to run for a second longer, but still did the same thing. This is all with the later electronic fuel injected system.

I can rip it all out and put kjet, but I still need to get a loom made up and is it really progress?

Any help or words of wisdom gratefully accepted.

I have a few alternatives, but am seeking guidance. help me wise ones.

1. Get the audi 1.9 factory loom working. Have been trying for two months and there is still too much spaghetti wiring.

2. I have an early jetronic system from an audi 80, 1986, which is a very simple loom and has an early computer. Will this work with a different engine code?

3. I can rob the kjet system from an early cabrio gti, but I have no loom. There are not many connectors, but presumeably the isv and the connector by the fuel distributor still need power?

Help me please guys, or I`m gonna make up an adaptor and whack a big carby on.

loon, e mail sent...

Nice one for your email roccodingo, that is a pretty clear diagram.

The only bit I dont understand is the thermo switch for the cold start valve. Are they connected in serial or parrallel? The diagram shows power coming from the starter solenoid to the cold start valve, that makes sense, but then does the wire go to the thermoswitch and then to earth or what?

Help appreciated here guys, I have tried three looms on this motor today and am now halfway through installing simple kjet. If I can sort these wires tomorrow morning, I`ll be going cruising. If not, I`ll be making an adaptor plate and whacking on a carby.
