Sorry for the delay and thanks for the responce.
JohnZ, you are correct in that the window relay coil (A31) was fed from the fuse box but the window motors where feed from the circuit breaker(C06) on the firewall.
A31 didn't have a firewall piercing - it was fed from the fuse block.
Joe, the power lead wire is different for 69 than for 67,68. Are you sure that your original reply was not correct?
