Does anyone have a spare plug for cab gearbox control unit - the metal cased one for bypassing auto in AEC engined RM? (I know the tree can be rewired for manual but an easier solution would be the plug.) Willing to pay a good price!

My bus number (if any): RM737/875/1353

Someone I know is trying to find out the wiring so he can produce some. Rewiring costs about 50p for the bits of wire. I had to do that to our rML when it was non-start in France the other week!

My bus number (if any): RML2532

There wiring diagram is shown in the first RMOOA Compendium of Technical Articles.

My bus number (if any): RM1368

Is that available online to members?

CAV 551 is the part number of the control panel, not the plug.

My bus number (if any): RTL 960, RMC 1458, RM 1585 and several RTs

In answer to the question from Roy, the Compendium is available to purchase by members or non-members, but is not available to view on-line.

This is the one for originally equipped RMs.

Thank you for all your suggestions. The tree has now been successfully rewired following a diagram kindly sent by Pete Rogers and forwarded by Martin Detheridge. No more auto (not that I used it much) – and one less thing to wrong, we hope.
