My speedo and tacho are'nt working on my L3 cluster i just finnished installing it into my excecutive would these things not be working due to the fact that i have not yet joined the yellow wire to my ecu?.If not please help has anybody had this problem before?.
I've taken it for a drive this morning and the speedo works now after a good old tap on the cluster but still no tacho.
Have you got the dash from a V8, and fitted it to a V6 or vise versa??
Tachos are different between the 2 engine sizes and will not work correctly if the wrong one is fitted.
The L3 cluster i brought was advertised as a V6 cluster how do i tell the diferance between a v8 one and a v6 one?
