Temp gauge setup for running the car [emoji23]


And working on a permanent one but for lower down , not in the vent . It’s going to be difficult to fit the gauges I have in this car without cutting or modifying but I have a couple ideas and don’t want to alter the dash .

So a couple solutions and another issue. I fixed the run-on issue, but I the fuel pump and cooling fan do not work.
I'll try to type this so it makes some sense.
I have done a few AAN swaps and always have used B15 to supply the 12V switched power to the harness. So with that in mind I switched the +12V Switched wire to the ECU from I15 to B15. In the diagrams, from what I can see, this makes no difference at all. But I can tell you that it does because the engine does not continue to run now. Odd
Second, the Starter. I was looking into old pictures ad recalled that when I initially got the car I had swapped out the fuse panel with one from a b4 (I think) to see if it would alleviate some weird starter issues. The panel that I put in has one thing different in position number 8 for the AT relay. As soon as I saw the old pic I realized why I needed a jumper for the starter. Swapped back my 'original to this car' 83 fuse panel and the starter behaves as it should.
Now with all that in place when trying to start the car I've realized the third issue.
I purchased the VEMS V3.3 ECU and a VEMS Base harness with the intention of wiring it myself, and had so many things on my plate I later decided to have Marc wire the harness for me because for the price its a no-brainer.
. With the laptop hooked to VEMS I attempted to get the car to start and cannot get it to start it seems because the fuel pump is not coming on with cranking. I verified this using a test light at the 12V supply to the fuel pump. So tried using a jumper and the car fires right up. With that in mind I now see (hopefully the reason) why the fuel pump relay is not triggering on and cooling fan are not working. The VEMS harness that he built for me has the cooling fan built in and relayed but the ECU was never set up for this it was just set up for base audi AAN. So looking in the settings I see that the cooling fan is set to off
Per recommendation above I tried
key on : laptop sees VEMS ecu connection
key off : Loses connection
*no fuel pump prime at any point*
Key on: Invert fuel pump , burn, key off *no fuel pump*
On the fuel pump just to double check I have tried 2 separate relays and cross checked both PN's / one is the older superseded PN but they both have the right connections on them so I’m fairly certain that it’s not turning it on / off.
