INNOVA 3123 GM OBD1 Code Reader, Windows XP

1989 Ford. Product worked perfectly. Connected to OBD 1 and gave me all the active faults. Very good product

Obd1 scanner works great cheap in price easy-to-use

Works great, easy to read and easy to follow instructions.

Great experience, shipping and quality

This code reader is very easy to use. It came with a book that explains everything, which is worth the money alone. Very handy and helpful.

Believe the reviews. The pins push right into the unit as soon as you try and connect it to car.I purchased the extension cable being I want to be inside the car with it running to check codes. Here is what I did to use the reader successfully:-Remove to battery and battery door-Using a flat head screwdriver carefully split the case on the scanner-Using small needle nose pliers, hold the pins from the back on the inside of the scanner-Carefully and slowly work each pin back thru the top of the scanner case and into the extension cable-Temporally electrical tape the scanner case back together-Insert battery and replace battery cover-Test unit on vehicleIf the scanner works correctly at this point, you can remove the tape and use some kind of adhesive glue around the edge of the vase to permanently reattach it. As long as you dont remove the extension cable, it will work as intended.The book of codes and instructions that comes with it is very good. Lots of detail and explanations. Without the extension cable, one would have to figure a way to glue or permanently afix the pins to the top of the case. Doesnt seem like an easy or lasting way.My take:Get the extension cable, follow some form of my instructions, be happy with scanner.

Pretty simple to use once you realize the plug only connects to 2 pins not all 3 and you put the plug on the right way.Didn't have any trbl with the blades pushing in...

READ BEFORE PURCHASE!!! Then 3145 model I purchased did not work on my 93 f150 4.9. The male pins on it do not match up the the female pins on my trucks data tes t plug. Made 3 jumper terminal wires with males on one end and females on the other ends I tried every (9) combinaton. Nope. Called Innova tech support. They said it ONLY works with 91-94 fords with the 7.3l engine! Page 7 of the owners manual actually list my particular truck but was told that was an error. I asked what model reader do they have that would work for my truck and was told that they do not make one!!! All the reviews must be a conglomerate of all their readers for varoius other vehicles.
