Tom5190 · 24th May 2014, 15:47

I've done a fair few loom splices for members on here & moaners over the last few years, it seems to have died off a little and I also don't really have the time anymore. I'm still doing it but not as many. Therefore I think its time I shared the info that I have.

I made these diagrams/lists myself, please take that into account. As far as I am aware over the last 3 years I've not had any problems with the working of any looms using this pin data. However I hold no responsibility if something does go wrong. Please note that the information needed is only really 30% of what's required to do the job, if you don't know what your doing in terms of wiring looms and general electronics, then I would urge that you do it with someone who does, or pay somebody else.

(I've not been on here in a while and I have seen a few pm's regarding fan info I'll go over that in here too)

Please see this thread to identify which chassis plug you have: http://www.saxperience.com/forum/sho...d.php?t=441413

IMPORTANT: The pin numbers on the chassis plug (engine side) count from right to left, all of the following info relates to the engine side. When 2 numbers are given i.e. CM103/CC2 this means that EITHER can be found on that wire, the wire does the same job.

Tips:

1. You don't need the immobiliser wires, if the ECU has been unlocked properly & the pins removed then they wont be doing anything. Immobilisers will not work on an engine conversion unless all of the necessary hardware is transferred with the engine.

2. Air-con wires are always there, obviously this is useless in the UK as our models never had it. these can also be removed from the loom.

3. The engine only needs 3 wires to run, that's STARTER, IGNITION LIVE & FUEL PUMP. If these wires are spliced correctly & you have no spark/fuel then your ECU is not unlocked correctly and/or you have a faulty Main Relay (Under ECU)

4. I usually leave the oil level & temp wires in the loom tapped up in case they are needed at a later date. However if you don't plan on using 16v clocks then these can be removed too.

5. I usually bridge the Lambda live into the CM10E ignition live wires further down the loom.

6. If you are going to use an early Saxo 16v engine, there's a 90% chance that none of the wire numbers are still there, also with only using 4 different colours you need to be careful, cut 1 wire at a time, buzz it to the plug to identify the pin and then splice it. Don't get carried away and cut the full plug off at the start you will cost yourself a shed loads of time.

7. MM100 earth in the early 106 looms isn't needed in a splice either, this can go.

If you fancy more of a challenge and want an XU10 or something along them lines in the car then the following link has most of the Peugeot wiring diagrams that you will need for anything like that. To my knowledge a Citroen version of this doesn't exist. - http://peugeot.mainspot.net/wiring_diagram.shtml
