No Check light connected. I plan to use the light you said (if you remember) was for over heat on other thread. My cluster did not had one.
I do not see any diodes near ECU but I suppose they may be near the shifter. Now do we need to connect this to Connector A as its already connected D. If Yes then I would straight away connect this pin to A07 with Diodes.
well not sure about that because my car already has one TCU. I do not see any wire from ECU going to my cluster apparently. I would have to figure out the cluster for that but not sure why di we need to cut the wiring.
If the car is in good power I would later change the transmission but first I need to work out the power issue and make sure the other functions are fine. .
Well I would figure out the main Relay. Rite now not sure where is it. Most people have problem with it but soldering works here. Not sure if this was a carby before the main relay would have fuel pump point ? secondly the car has CNG so we have to make sure on CNG the pump stays off.... at present the guy has run complete wire from relay to pump. He is not using the original yellow wire. in worst case I think I should connect the existing relay connection after CNG switch to the ECU Pin. .
well somewhere I read that odb2 ecus read rpm via ckp I suppose so if you want to run rpm in this cluster you should have to get a wire from distributer ignitor. there is a single wire coming out I suppose it is for that purpose. Its a good idea to connect lamp to MIL and get the codes by checking the SCS service check signal with a switch to get MIL throw codes if I am not wrong. Other than that I was driving yesterday from Lahore to fsd it came to my mind that if ECU is not getting the signals from starter or Power switch signal then how come car turns off the AC while I am cranking and once car is start then turns on the AC automatically. How come car manage the timing or spark adjurstment or injectos if it knows car is not powered up........ strange but can pathan touch the embedded systems in side ECU to do bypass, I personally think its not possible as I opned the ECU and did not find any re soldering or jumpers as the pcb board is SMD so there is little chance they can alter that circuit........ In regards of Pictures would upload once again
