To those of you who have installed the AeroForce Interceptor gauge (on SS/TC), have you installed it using only the OBD2 port connector, or have you installed it with the extra 3 wire mini connector (which has the middle red wire connected to a switched 12V source and the red jumper removed)?

I'm curious to see what most people have been doing. I'm leaning towards connecting the 3 wire mini connector to use as the power source because I don't want the gauge to remain on anytime after I turn the ignition off. It seems like the only way to make the gauge operate/behave the same as the stock gauges is to do it this way. Thoughts/suggestion??

 

OBD 2 port . If you turn the car off and it stays on which it will do very rarely. Cycle the key and that works or just say f it like I do and let it time out after 10 minutes. The drain that little thing does in 10 minutes is nothing.

 

you only need the obd2 port

 

Obd 2. Mine stays on for about 30 seconds after i turn the key off and open the door. No biggie.

 

Cobalt does not use the extra power cable, like everyone above me, OBD2 port...

 

I'm another one using the OBD2 port connector for power.

 

I'm under the impression the 3 wire is only for the ss\sc.

 

Thread revival, i have this exact same question!, dont really see a clear answer to, ppl just saying im using the OBD2 port... so, can you simply use the OBD2 port in a TC for everything? no need to run the power cords cause it will draw power from OBD2 port correct?

 

Correct. just plug it in. IIRC I removed the little red thing on the back

 

Right. plug in just the OBD2. All you need.
