I have searched and a few times i thought I found the answer but no.
So the question what temp sending unit or ECT sending unit.
I have researched 2004 cbr wiring and vtr wiring and they are some what different. it looks like the cbr is a two way switch maybe.
two ecm wires
1 Gray/Black a few sensors piggybacked with ecm wire pin at #26
2 Blue / Yellow to pin #27 to ecm

Last one is a Gray/Blue to dash but along the way it changes to a Gray/Red somehow. also I think from the forums it is the same thread.

Any help would be great.

Difference between the sending unit is they are inverted on the ohm scale.
