I'm in the midst of restoring an 89 325ix (production 9/88). I've got 2 wire sets that I need help with. Both of these are on the driver side of the engine bay. The first is a bundle with a blue/brown wires...looks like the plug got ripped off...it terminates through the firewall through a grommet under the fuse box...my searching makes me think it is the ambient or outside air temp sensor??? Am I correct? The second is a blue 2 pin plug that comes off of the main harness near the coolant reservoir. Its a very short run with a purple/black and a brown wire...Im stumped with this one. Any help or info is much appreciated. Thanks

Just to follow up...I found the answer. The blue plug is part of the wiper/washer system. The wires are violet/black and brown/black. According the the US wiring diagram Page 6160-0 they are not used....however it appears that it is used on euro cars with heated washer nozzles. Thanks all for your input.
