Speedometer doubled, odd cluster problems

[Blaine0002]

When I am driving, my speedometer seems to be doubled what I am actually doing, I have the proper coding plug, so thats not the issue (m20 -> m50tu)
My vehicle speed sensor is wired from the green plug to the dme..

I figure this may be effecting why it doesnt start as easy when its warmed up (takes a couple cranks and doesnt idle right away) but when its cold it starts up perfect..
That and the coolant temp isnt getting a reading. im gonna replace the cluster sensor and see what happens (maybe I should just replace them both?)

What do you guys think?

I replaced both sensors, and im still not getting anything for that.. I have it wired right... Should be brown violet to brown violet thru the c101 / x20

go by pin number, not color

[Blaine0002]

it was by pin number...



I did my homework in the ETMs...

Didn't doubt you fully, just making sure since you only mentioned colors.

Have you tried grounding the coolant sensor plug? It'll ping the thermostat to max temp indicating your wiring is correct.

i assume youve got that plugged into the brown base sensor?

Blue sensor goes to ECU, Black sensor goes to cluster... Brown?

^Problem A:
Black base sensor is for E36 Cluster. You need an E30 one.

Woot, brown plug fixed it for me!!

Now my only issue is that my speedo is reading about double.. Any ideas?
