Hi all i need a bit of help to identify where these plugs go im fitting a 90 spec loom so a couple are mk3 golf ones and the rest are cupra R, S3 ones so here they are simple one single red wire i think it is for the starter motor. next is red /green and brown black wire i think it is reverse light next is off the cupra loom i have no idea it is blue/white and purple/white? next is this 4 pin plug no idea colours are red/blue red/grey grey/white grey/yellow next is yellow/blue purple/grey grey/white Thanks in advance and i have more to add soon
On my car the wires are pretty well protected by the corrugated cover and did not want to rip it apart. Luckily I have all the OE Seat 1M LCR diagrams and have found what you are looking for. Picture 1 is for the starter solenoid and is know as KL50. This does look like an older connector from a Mk3. Picture 2 is from the Leon not Mk3 and that is F4 the reserve light switch. The wires flyleads are 1mm dia and are brown/black and red/green. Pictures 3 to 5 are identified in the illustration below. Note that F88 is not blue/white but is actually white/grey (ws/gr) of 0.35mm dia. The rear HEGO sensor will not be required and the driver can be turned of in the calibration. PAS switch up to you. The OE calibration is usually in the torque reserve for AC and the PAS at idle, so if you load up the the accessory drive by applying a full lock via the steering in idle, the reserve for the steering load will be released to maintain idle speed. Hope that helps
Just a few more There are 2 wires blue/yellow and purple/red next is a 90 spec plug 2 wires brown/white and white/red last is this 4 wire plug think it is for the maf but only 4 wires? blue/red, yellow/grey, grey/white and red/grey cheers again
First picture is the purge valve N80 The 2nd picture, pass as I do not have my MK2 reference in front me. The 3rd I sure looks like the G130, already defined in post 5.
2 is the outside temp sensor for MFA, its a mk3 type plug tho not mk2 you can get a sensor that fits from G60 and early corrado/passat, the mk3 sensor isnt right rating for mk2 clocks . or just splice mk2 plug on
Late Mk2s do have 2 pin square connections. It is not clear but the wires also look like the typical 1mm flyleads as well. You sure that is the function? Nathan, I take it your car was a 16v and the 90s loom is the original from this vehicle?
Mine was a 16v mk2 but when sourcing a new loom I had to go to a mk3 one as could not get a mk2 one at the time
I've never seen a 90spec mk2 loom with this plug on the MFA wiring, but it doesnt mean they dont exist of course! There are many wee differences on later run out spec this could be one of them I know that the G60 mk2 had this kind of plug on it for whatever reason. Mine is the usual mk2 type plug but its an early 90spec and doesnt have some of the changes the later 90spec have! the wire colours are correct as is the wire gauge size so I'm 99% sure thats what it is anyway, to double check the wiring goes back to g1/2 and g2/2 but if the donor engien loom was a mk3 then this plug would be correct, the only issue with mk3 is the sensor is on driver side not passenger so it wont reach the factory mk2 position, you could just find somewhere handy and mount. you may find the hole for it is there on the driver side wing, im not 100% if the pressings ae identical for both sides here
Lol think that's about done I'm only worried about the ones that affect the running cheers guys No wait! I have another Lol the MAF plug is a 5 pin D plug? Cheers
