I gotcha. And nope, I had no issues and both of my cars have immobilizer. I’m not 100% sure but I doubt the immobilizer has anything to do with the cluster aside from the security light. Like I said I had zero issuesNah man changed out the sending unit same deal, it's at the cluster I think anyways... is there any security features to watch I out for? Or is it just modify pins and install. Someone said when you change cluster immobilizer might FSU could be wrong tho.
