172 Wiring Diagrams

[James5_GTT]

Anybody on here got a copy of the wring diagrams for the 172 I am attemtping to identify the pins on main loom plug?

What does everyone use for the wiring manuals??

Which bits to you specifically want?

 

[James5_GTT]

specifically main connector of the Engine loom and what pin does what.
For the white connector in this pic

This a loom from a Ph1? Just looking i've only got the Ph2 diagrams.

Yeah it is a phase 1 but if you have phase 2 diagrams i suppose it is better than nothing i assume the only real diff between the 2 looms would be the TB

And multiplexed wiring so it might be completely different. Where is that plug? I don't recognise it.

We found when we were doing our conversion that finding the diagrams is next to imposible but to be hoest if you know how to drive a multimetre it's a pretty simple loom to work out. Getting ours running only took a bout 4wires and the rest were just guages and lights we had no wiring diagrams to do this we merely used the continuity tester (on the multimetre) to find the basics needed, Permanent ecu live, ingnition ecu live, cranking signal, fuel pump wire (from relay on engine loom and we have a relay map if you need it) and that should be enough to run a decoded engine.

If I remember rightly we used auto data phase 2 wiring diagrams to find the ignition and permanent live to the ecu and they were the same however little else pays any relevance.

Hope this helps. Chris and Moo

Perfect many thanks I will give it a shot.

buy yourself a power probe and a multimeter.,
diagrams arent worth the paper they are written on, takes a bit of head scratching but you can work pretty much anything out using those two tools

Cheers matey already got a multimeter just ordered a power probe

Think i will take you up on the offer of the relay map.

pm for you
