88-91 Chevy GMC C/K Truck 1500 2500 3500 odometer and trip meter. Bench tested, works great. Good condition overall. Comes exactly as pictured nothing else included.  201k miles.

Note, pay close attention to the plug, there are different styles/sizes!! This one has the hard to find tab (fits circuit boards with part #600). I offer both styles so returns will not be accepted if you buy the wrong part. Message me with a picture of yours if you need confirmation.

I need parts!! I will issue up to $20 refund if you send me your broken core, message me if interested.
