hello there. and thanks in advance for your help.

1-) could someone please post a techsheet for the 96 jetta.

2-) I was browsing the forums and someone reported that the parking lights and trunk release have to be isolated by relay. Would you please clarify and tell me how to wire this relay, naming each prong and to where it goes? thank you.

for the trunk

30 = trunk side

87a = switch side

87 = 12v

86 = 12v

85 = negative trigger from alarm

so for the parking lights i'm assuming this is the way it goes. please correct me if it is wrong.

1st relay

30 = lights side

87a = switch side

87 = 12v

86 = positive output from alarm

85 = ground

and the same for the second relay. thanks.

tach- try to find the green at coil(could be different colour) test the tach wire for AC Current it should be between 3-5volts and voltage should rise with revs

is there not a wire on the handbrake assembly for the handbrake wire

k guys. i went to the CC roadshop today and asked one installer do help me out on this one..... he checked on W/E database they use and the TACH WIRE is BLACK/ Red... i checked the coil and it match with my vehicle....

About the Hand Brake i'm going to research a little better... it should have something on it..... reason is that in the cluster.... there is a BRAKE light wich lights up when i pull the e brake. thanks.
