I am installing a 2005 5.3 in my 1972 Jimmy. I am thinking of adding one of these gauges. http://www.aeroforcetech.com/ Do I still only need those 4 connections or will I need additional connections for it to work?

Thanks

 

Yes those are the only 4 wires needed. Not sure if that guage plugs into the OBDII port or taps into the wiring, but either way would work.

 

That gauge plugs right into that OBDII port. What are those other wires for then? Will you gaurantee that gauge will work without them?

Thanks

 

A quick scan of the manual says you do need the OBDII connector as their harness simply plugs in at that point and uses the data stream normally used by a scan tool.
Direct quote of step 4 from page 3 of the manual "4. Plug the main cable connector into the OBD2 connector. See figure 2. The
data, ground, and power on most vehicles come from this connector."

The device looks interesting, but a nice scan tool is portable and does the same thing for about the same $. However this does have the handy option of doing a case relearn. Now if they made one that would replace all the gauges and senders that ran direct from the OBDII bus...

The manual in PDF.

 

the factory ALDL connector only has 4 wires in it. (or at least the one that I pulled from a 2004 silverado that I got my wiring harness from)

 

The other wires are for other systems in other cars like ABS, airbag systems, different modules ect. I can guarantee you that a scanner will work without them, it will just read the powertrain. My TechII will read powertrain, but says there's no communication with the other systems. If it plugs into the OBDII port, then all that gauge really is is a small kind of code reader/scanner.

 

Thanks, you guys are the best!

 

The reason I am considering it is I am installing in a 72 Jimmy and keeping all my factory gauges which are not the most acurate. I just figure this will be a cool tool to monitor everything the PCM can monitor?

 

I know what you mean
I'm using autometer guages in mine. I'm also considering running a car computer with a pop out touch screen popping out of the ash tray.....then I can run HPtuner while I'm driving and just display it on the touch screen!

Have you seen the guage pod that is formed into the dash pad? That might be a good place to put that one or the hole where some trucks have the air pressure guage for bigger trucks.

 

Now I see the light! This could be a possibility for my 61...

 

Thats where my not very acurate factory tach is

Have a link to that dash pad?

I havent really looked into mounting locations yet, don't even have my engine in yet. I don't even have a working crossmember yet! (4X4 unlifted trucks have a few issues, I believe I have everything worked out). I may try to locate it in a radio delete plate since my radio is in a lockable center console (convertible needs lockable storage).

 

Another option?

Sweet. I like the data logger but it isn't OBD II.

 

And pricey

 

I think he's talking about the small gauge opening just right of the steering column, it looks like it would fit there.

 

How do i put wire OOBII connector and a check engine light in to my 2003 5.3 harness, do anyone have a digram

 

I'm not sure how much different your dash is than my 82's, I was going to buy a 6 gauge set that would work with my lq4 and keep it looking stock, but got a digital gauge from Summit. I took all my gauges out and bolted the summit one to a metal plate then mounted it where the old one was. It was only $260 and I have a tach fuel temp volts oil and speedo.
