My wires are free to move if they desire (not a lot though). Granted my wires in the cat are reasonably short, they are longer than my original install where they ran down the side of the chassis. they now run the width of the speedo then round to the motor. I think slightly longer than the original install. I wouldn't of thought pulling on them should do this. they would have to get hot enough for the solder to let go wouldn't they? I think durango installs have shorter wires than mine... come to think of it I wouldn't have said they were much shorter than in the B44. When I 1st got the cat I just lifted the speedo out of the B44 and straight in without touching the wires.
Last night I installed the original power cap and ran the 10.5 all night without any problems at all. fantastic motor for ludlow!
I will continue to monitor the issue now running the 10.5. This was geared on 23/81 and temp gunned at 136 after a race with 2-4 warm up laps.
If it's the speedo at fault I'll treat myself to a new Pro version
