Recirculation Pump

[mikecg]

Hi, I have been viewing Tuga's video on how to fit the Mercedes Pump as a replacement for the original. I have not ordered one yet but they are now very reasonable.

Mine appears to have slightly differently wiring to Tuga's car.
Firstly my connection from the pump to the wiring loom is behind the nearside head lamp outer housing and it is also only one wire to each connection from the loom instead of two as Tuga shows us on his car. It also may just reach the pump with a bit of manoeuvering. As indicated the Mercedes pump has the same connector as the Elan pump
I have a Black and Black/slate from the loom which is correct. They inturn connect to the pump wiring a black and a brown. However in the process of removing the pump I split the loom conector (it comes apart) so I dont know which colour from the loom went to which colour on the pump? The wiring diagram does not provide the answer.. Some help here would be great?

A bit hesitant in putting this forward, I have checked my S2 and the pump Brown goes to loom Black and pump Black goes to loom Black/Grey. I was surprised, thinking that convention would be black to black (maintaining a black ground colour through the connector). Its probably worth checking pump flow direction before plumbing it in just to be sure, I assume the pump should suck on the center port and throw it out through the offset port. If you gain any knowledge on this it would be useful to post the outcome here. Good luck.

Remember the recirculation pump pumps in the opposite direction to the normal direction.
