What I mean is that I think everything is directly connected to the ecm (because when connecting the pc I can see all the info) and nothing to the cluster and that is why the cluster does not work. That is why I ask that if I have it like this, if it is possible to put a cable from the pin where each sensor is connected on the ECM to the cluster to have the signal divided into 2 and be able to see it in both. Except for the tacho and engine light tha is diferent

Yes,all the fuses were ok

Okay i see. Thanks a lot! I will do more investigation job. So i think that all the sensors are just conected directly to de ECM an not to the cluster. Can i put a parallel cable that goes from the sensor to the ecm and to the cluster? Is not gona affect the meassurements?

Okay, so i just checked the ignition-12v and grounds and it is good. What i found is that the illumination cables(+ and -) are not good. Bouth pairs are bad. They are shorted to ground because i can’t get 12v between them, i get 12v touchin the ignition-12v with ill+ and also with ill-, ill+ and ill- have continuity between them. so for sure theres something wrong, i will check the cables later. But this is for illumination sistem, can that provoke that the gauges are not working? And what the VSS means? Can i check that pins also? Thanks a lot 😊

Hello everybody, i’m new here 😀. Straight to the point, i bought a r33 gtst. The car was originally with the rb20 and then someone did the swap to rb25det and put a Vems v3 ECM. The problem is, the cluster is not working at all (no lights, no gauges etc). But if i conect the computer to the ecm i can see the speed, rpm, boost, temps , everything. I took out the cluster and checked the conectors and looks fine. I also checked the fuses and all were fine. Can be that installing the aftermaket ecm they didn’t conect the cables to the cluster and plug them directly to the ecm or something like that? How can i check that? Any other idea? Thanks🤗🤗
