Not impossible to pull the pin out, I did the lot in under 10 minutes from start to finish. Gauge now works like it should. I used a pair of really small needle nose pliers and a jewllers flat tip screwdriver. As you look at the connector, Slide the flat tip under the bottom of the pin. Pull on the back of the wire and give it a wiggle and should come out with some pressure. A small amount of rebuilding of the pin and I put it in the right spot. PERFECT working oil pressure gauge!! Some original photos have not been recovered yet.

Does anybody have a pic of where the oil pressure sender goes? All I should have to do is to unscrew the old switch one and screw in the pressure sender? Plugs into the same plug? I'm not real good with mechanics, but I want to learn how to do stuff myself :S LOL. I just need to know what I'm removing/swapping over. Oh, what tools do I need to make the swap? Also the tacho should just work when I plug in the new cluster, correct?

yes the tacho will work. I put a Berlina Series 1 dash in my Series 1 SL and it works fine. The oil gauge will not work without the berlina gauge cluster harness. The oil gauge is located just to the left of the oil filter and needs a spannes to remove (not sure what size) if you feel in where the sender screws into the block you will find where the spanner goes. From memory you need to remove the starter and maybe the oil filter but it was a while ago I did it and cant remember for sure.

I fitted a Series one berlina dash into my series 2 exec and the tacho doesnt work. I also fitted the loom that plugs into the cluster from the berlina into mine aswell so I dont have to change the pins around as it already has a wire joining pin 14 and pin 2 together. Could the tacho be stuffed or do I have to connect something up?

not sure but it sounds like the tacho may be faulty

Did u swap the oil pressure switch over with one that is for the gauge. The sender unit that only operates the idiot light wont work on the gauge. Is there any way that I can test to see if the tacho works?

To check if the tacho works you have to start the engine Some original photos have not been recovered yet.

Im still yet to put the pressure sender unit into mine becoz the gauge goes to full scale. Just have to get round to my mates place and get it off his car. I started the engine after I plugged the harness in and all the other gauges and lights work except for the tacho. I was thinking there may be a disconnected wire or dud tacho.

This is what I did also. It was a ******* to get me hand down my dash to undo the plugs. Now im having speedo problems, snaped the cable at the gearbox end and replaced it, now its making squeking sounds. I have the sender unit, here is a photo of it www.geocities.com/ur_car/HPIM0976.JPG (http://www.geocities.com/ur_car/HPIM0976.JPG) I was just wondering if this is the correct unit. There is no plug in my engine bay to fit the connection on this sender. I had a look where the sender unit in my VL is and it is a clip on plug not a slide on connector. Can I just this this wire instead?

Can I just this this wire instead? there should be two wires there, one for the light and one for the gauge. it might be taped onto the main hanees, check and you should find it.

I was wondering how would you clean the oil sender? The engine that I took it off looks like it hasnt had an oil change since new, I took the rocker cover off and the oil was baked onto everything. The oil pressure sender works, just want to clean it to unclog it abit.
