I have a 90 Camaro with TBI. I installed an 89 MAF TPI system with an 89' 165 ECM using an 88 MAF Harness on my car. I am confused on the VSS because I dont want to make a mistake and by the wrong one. I know the car uses the VSS for important reasons. I figure I should by a VSS for an 1989 TPI Camaro. I just dont know what it looks like. Could someone please help me out here
