hi every one i need some help finding a aldl obdll diagnastic port for a 96 z28 camaro. i have a 96 5.7 lt1 in my 91 z28 and i need to get the odbll aldl so i can get the codes read off it. my engine is not running right. i have the signal and ground wire connected to the 91 aldl port but i have no way of checking it the way it is. i also have a lap top i was going to use but i cannot find the cable i need to hook it up to the aldl port of my 91. i was told you cant do it. or no cable was avalible for this. if any one can help or info on where i can get one would be great. thanks guys

 

No idea . I may be wrong but I only see three way you can do it.

#1. Figure out how the OBDII cables are made and custom make one for your own vehicle (hardest).

#2. Search salvage yards for a fourthgen OBDII connector and splice all necessary wires from your pcm and use a standard OBD II hook up cable.

#3. Convert to OBDI.

Sorry man, wish I could be more help =/.

 

Contact Speartech via www.speartech.com and see if he'll sell you the connector hood and a few crimp pins to go w/ it.

He sells an OBD-2 bench harness that uses the conventional OBD-2 connector hood.

 

thanks i just emailed speartech to see what they got

 

I have an obd II diagram around here somewhere, and a connector is $2.39 from dealership, but #2 is the easiest, as teh connector from dealer is just that, connector w/no wires/leads.

I'm really using 3 leads:

12+ (fuse)

2 grounds (spliced into 1)

serial data lead

2 rows of 16
