Can anyone confirm if my data link wires are spliced correctly?

 

I spliced the wire from truck wiring yellow/blue line with the solid blue wire(B) in the quad data link harness. I then spliced the other wire from truck wiring yellow/green line with the solid green wire(A) in the quad data link harness. There was also a black wire (truck wiring side) but i did not wire that to anything.

 

On the quad harness there was a 3 prong connector labeled A,B,C. A was solid green wire. B was solid blue wire. C was no wire.

 

Also I dont think it has anything to do with what I have done but my speedometer does not work now.

 

I really need to try and get this all figured out. I finally got the truck back after leaving it with a body guy for a ton of body work and paint the last 10.5 months and I really want to enjoy the truck before I have to store it for winter in 2 months.

 

Thanks for any help!

I've looked at this diagram 10 times just noticed the A,B,C 🤦‍♂️🤦‍♂️🤦‍♂️

 

I feel really stupid rn. I hope that is all I need to do is swap them wires. That would be fantastic lol. Will find out tomorrow! 

 

I just hope I didnt cause any damage connecting it wrong..

 

Thank you for your help and pointing out the obvious Me!!! 😅

Finally got the quad hooked up.

 

I had a short somewhere in my data link wires from ecm.

 

I cut the wires just out of the ecm and spliced the quad to that. Success! 😁.

 

Also to note. I was misinformed on the quad data link color wires. I said (B) blue and (A) green.

 

The CORRECT quad data link wire colors are (B)purple and (A) pink.

 

So the correct connection is (B)yellow/blue stripe to (B) purple. And (A)yellow/green stripe to (A) pink.

 

Thank you for your guys help.
