One of the main power lines is black. All non-ti e36s have the battery in the rear but are set up in the same manner when put in a ti. |
good to know bluey! then he definitly has something wrong if he only has 2 wired up. |
for the smaller connector ive got one other than the maf with only 4 wires. and the car it came out of seemed to have a front mounted battery, also i cant find the third wire that connects to the battery. where does it come from and what color wires are in the loom? on a whim i connected the black wire that seems to be the ground under the diagnosses por to the battery and it lit up the guages withe the key out, that loom seems to only have brown wires in it. that is a ground right? at this point im thinking it may not be an obd1 engine. the car was made in july of 95. didnt bmw switch to obd2 half way through 95? ps: thanks for the help fellas |
All m50s are OBDI, there is no variable there. The other connector, is it circlular like it belongs to something major, or is it to the traction control throttle body? All non-ti are rear battery mounted man, the connections to the battery are in the front though along with the diagnostic port. Two lines come from diagnostic port harness. The other is the main power which is positive. Went back out to the car and noticed that i had a few things wrong...thats what happens when you do things from memory. :P http://i123.photobucket.com/albums/o...Layout11-1.jpg |
the other4 wire connector i have is identical to the x20. correct me if im wrong the x6031 from the ti only has 4 wires as well. the two connectors do not have the same color wires. above the diagram seems to only show two wires running to the battery(or maybe im confused) also for the x6031 plug it states that we dont us it and just cut all the wire, correct? ill post pics of what i have in a few minutes |
|
Im still pretty sure you need another power wire hooked up there... I don't have my car for reference at the moment though... but it could very well be different since im all OBDII and using the M52. |
|
Dont cut the harness off like that pic says above, its a waste of time and youll ruin the harness. |
Also, do you have a base, sport, or active package? |
im still confused because the connector on the right has far too many wires compared to mine. are thes different options im assuming. the four wires on mine are all white with varios color tracers, also should i use the orgional connector from the ti or the one from the is to do this? im unsure what package the car has, (fully loaded exept fog lights) i apologize for my shortcomings of e36 knowledge, im still learning the bmw stuff. lol |
Well, looking at your harness and such, youre obviously missing some prongs on the second connector. Do you have the three-button On-board computer that is installed just to the right of your stereo headunit? Do you have cruise control? If anything, you should be able to do the swap using the numbers posted up above on the corresponding connector. As far as harnesses go you should be using... M50 Complete engine harness 318ti chassis harness M50 DME (ecu) When doing the OBDII to OBDI swap youd also be defeating EWSII and in the end you should have EWS0 meaning no EWS at all. When you make these simple connections (changing the chassis harness lines) you completely defeat EWS. Another question i have for you, is the label on the ecu silver or red? It should be red in order to do this properly though youd be able to defeat a silver ECU EWS by cutting the line to the EWS function. Also, did you slide the ECU into the pronges in the firewall or just sitting somewhere just in case you need to do something else with it? It gets grounded when you put it in the firewall. |
the car does have the on board computer and cruise controll. i believe the label is silver but ill check when i get home. the ecu is in the firewall and bolted down, ill check that out again too. |
M50 Complete engine harness 318ti chassis harness M50 DME (ecu) but exluding the connector with only 4 wires (in may case) correct? |
