C101 pinout Needed. 318tds - 25tds conversion help

[Bracky]

Hi all, this is my first post on here but hopefully not my last.
I have just brought another compact but have been playing with diesels so my choice was for a 318tds. Up to now i have had an e34 525tds which was fun with around 200bhp but its too large well its perfectly capable but who can argue with a better power-weight ratio so breaking the e34 to make a m51 325tds compact.
The problem is I am unsure if there harness will just clip in or need modification so i need the pin out data for the main engine harness to loom connector (called C101 on an E30's). Also would be helpful if someone has the info for the e34 side. 1997 318tds / 1993 525tds
Thanks in advance,
Brad

Yeh i always thought that was a shame, could do with more people to talk to about it.
Anyway I've got the x20 sorted. 4 etm's, multimeter and a real shock how easy it was compared to the c101 on my e30 (i dont think there was more than 1 wire which was correct).
Right, onto X69, all i can find is 3pins and nothing about the electronic throttle setup
S50B32 X69 pinouts:
10 Oil temp switch
11 Fan control relay (from DME)
12 Oil level signal (from DME)

Please help someone i only have a week to finish and theres so much more to be done after this.

got the x20 sorted and think the x69 is fine but the throttle stops after about 10% and it drops back to idle, there is more than one wire for the pedal what is going on?
i know this is a diesel and may not be of interest to the general bmw population but i have to have the car running by Friday as i have a 600 mile journey to grandmothers funeral and could really do with some help with this.
PLEASE PLEASE someone HELP

might check over on bimmer forums or another site with where there may be more knowledge of the diesel system. post up pictures of the finished project definitely sounds cool!!

Turned out to be crappy positive to the starter/alternator so thats another one down but still no end of problems.
The temp gauge starts at 3/4 then goes into the red as it warms up and settles just before max, has anyone had this or is it likely to be a dodgy ground or could it be connected to the wrong signal (X20 pin.11 Brown/Yellow)
To top it off i have the injector light staying on but doesn't seem to be affecting the driving

[Bracky]

sorted loads today and its physically ready but still has injector light and its slow as a pony. the light turned off but has been intermittent ever since, definatly seems to be running smoother and a tiny bit more poke but nowhere near as fast as it should be.

Any ideas?

this thread has been a bit of a flop so i'm going to give up on it here, we missed the funeral and the car still has problems but because it has evolved so far from the thread title I'm going to open a fresh thread.
Thanks to anyone who gave this a read
