What are these?

[elimin8tor65]

I just bought my 1987 silverado. It has these two push pull knobs located just to the right of the steering wheel. Also has two round red led lights under the dash. The truck has a 350 with edlebrock intake and carb, no EFI with factory A/C. I looked on the carb for maybe a choke cable but choke is electric. Please help me with this one. Thanks!

PO custom add ons? Follow the cables to see where they go. Same with the wrong for the light. Definitely not anything original afaik.

You gotta run the wires down and see, it doesn't appear to be factory to me.

Not factory is what they are.

heads up...need an intro and pics of truck or you'll get grief...just sayin'

Welcome from Austria. Trace the wires. Post pics of your truck.

As others have said trace the wires and cables back, then remove the stuff and repair the damage.

FWIW, touch the area you want in focus when taking pictures.

Intro with pics complete.... well I took Yall's advice. Seems both cables run to each side of the truck just in front of each fuel tank. Not hooked to anything.... either fuel or exhaust??

Sounds like the PO may have planned to install cable-operated exhaust cutouts.

If the truck has a SM465 transmission in it, those cables could have been for a PTO, or a previous owner thought about installing one. One cable for on/off and another for direction.

Or the PO wanted install manual fuel selector valves.

 

[idrivea2002golf]

I was leaning toward manual locker cables but they do seem a bit small. Possibly exhaust cutouts as mentioned. Not sure why the red light if it's for exhaust cutout... I would think one would know.

Sounds like the PO may have planned to install cable-operated exhaust cutouts.

Or maybe ask the PO "wth were these for?"
