When ECU power cable (1) has been pulled completely out of fixed roof beam (2), there should be an
adequate amount of twine/rope left at circuit breaker box end to allow for pulling rope back through with new
ECU power cable (1) attached.
4. After old ECU power cable (1) has been pulled through, remove twine/rope and attach to new ECU power
cable (1).
5. At circuit breaker box end, pull twine/rope through fixed roof beam until correct amount of ECU power cable

cable into fixed roof beam (2) will make this procedure easier).
