T7a/4 I have connected to the golf mrk 4 header tank..Currently when I turn the key (not starting engine) warning light flashes and then goes out (telling me the level of coolant is OK)...it's meant to flash all the time at the mo..I have no coolant in the system yet!

T7a/2 I have used and connected to the Volvo temp sender. Open to further investigation as I have never had a temp reading.

Here is a flick of the fuse box and connections the van has..had to give it a good dust down..

I havn't messed around with the connections but curious as I am noticed this little puppy tucked away...not easy getting a flick part number
251 919 505 12v 70A..I believe it is for the radiator fan 2nd stage...Another area I need to investigate..when I lost the jx engine last year and it over heated..not once did I hear the Radiator fan kick in!

To finish off I took a flick of the starter motor..One reason is I needed ask a member who has the same to confirm the spade connections..I would like to know what the perpendicular spade connection would be used for...
The red and black wire I have (now) connected to the lower spade horizontal connection I believe is marked 50...its not connected as shown in the photo.

Back in a moment jumping post...
