Autotap is for OBD-II GM vehicles, you'll need to find your own solution for the 95. I know SSEi95 has one.

Incorrect, 94 and 95 have the Hybrid OBD 1.5. OBD I connector but you need a OBD II reader

Thanks guys for the info, but I'm still confused I need a OBD 1.5 but the autotap is considered the 2.

Or...

regular autotap with a OBD 1.5 connector

sorry in advance for being a pain,

Rob

Nope. It'* a OBD2 connection but still a hybrid OBD1 PCM. They installed all the OBD2 hardware in the cars that year but kept the programming OBD1 compliant. All though ruor has it that the programming itself is a hybrid of it'* own and encompasses new settings not found in normal OBD1 PCM'* but are found in OBD2... but that was a rumor I eard a while back.

So I'm out of luck. I guess I'll call autotap and see.

robbull,

I cobbled an L67 from a '95 SSEi into my street rod project. I purchased the PC based EASE scan tool for it. While it is more expensive than the Autotap I am pretty happy with it. It is specifically for OBD I. You can purchase (for a few extra bucks) the OBD II connector. My knowledge of all this business is limited but it seems to me, after swapping in my L67 and building the harness, that the ONLY thing OBD II about a '95 is that connector. For instance, ALL engine DTC'* are reported from a single source, circuit 800 (tan) PCM pins WD1 and WD2. (Serial Data). In my case, to save a coupla bucks, I ordered the EASE scan tool with the OBD 1 connector and hooked up only 2 wires. Serial Data, and ground, since I am not interested in status or DTC information on other systems this works just fine for me.
I included the following link on a thread a while back but (1) in case you missed it and (2) if you are interested, here it is again. It gives you an idea of how they have set up their software. BTW, this album describes how I found a wiring problem I had introduced into my TPS circuit.
