hello again need some please i have put a 9a engine in my mk2 its running carbs
since i have put it in the oil light has been flashing i know it has oil and pressure is ok
what i need to know is what wire goes to what sensor that will make this flash when disconected
thanks in advance lee

if the sensor wires are swaped that will bring the oil light on

im sure i got a greeny colour wire to front sensor and a yellow on rear both on oil cooler positive thats how they came off the 8v lump ?

sounds like you have used the old 8v wiring, which will mean your sensor wiring is wrong.
the green/black wire ids for the oil temp, and on the 16v this sensor is on the back of the head, not the oil filter housing. on the 8v the low oil pressure switch is on the side of the head, with the blue wire going to it.
You need to extend the blue wire so it reaches the oil filter housing, the blue wire goes to the black/blue/brown sesnor, the yellow wire goes to the white sensor. Then you'll need to extend the green wire to reach the back of the head, if you're bothered about the MFA working. If you're lucky the 9a will have 3 sensor holes on the filter housing, if so you can move the oil temp sensor into the filter housing.

cheers for the help guys

if its a small single pin one with a black colar, yeah thats the coolant temp sensor for the dash.
the single pin one on the back of the head with a white colar is the oil temp sensor for the MFA :)

rite scrapp last post lol went out and done it but light still flashing
but i think i might have wrong sensor in there
do u know what colour it is and if it the same as a kr front sensor
thanks lee
-
do you still have your old engine? if so whip out the sensor from the side of the head and swap it over, replace the black/brown/blue sensor thats on the 9a. the white sensor should be fine, otherwise it woudl be buzzing over 2k rpm.

sorted cheers m8 it dont flash any more and i can take the bit of black tape of the clocks now :grin: :grin:
another quick question on the 8v i take it that the temp sender is in the plastic pipe coming out the front of the head ??
so which one of the plugs and what and were would i put them to get the correct reading thanks
lee

yep it is, its the black one with the red/yel wire. snip the plug off and run the red/yel wire to the 1pin sensor on the side of the head with the black colar. the 2nd wire is no longer used, tape it up or follow it back and chop it off.

cool cheers m8 :smiley:
