Hi all,
Sorry if this has been covered before but had a look around and cant find anything! In the middle of a Honda conversion on a Exige S1 and in dire need of a pinout diagram of the cabin side of the bulkhead engine loom connector.
I am trying to connect a Maidstone Link Loom with 13 splices but don’t have a reliable diagram to know what colour goes where!
I have the Exige S1 service manual but not proving to be too helpful.
Any help would be greatly appreciated.
Cheers,
Rich
Hope this helps a bit …

Or are you after the Honda engine loom and ECU pinout?
Thanks for the info Andy, think that’ll help me out, much appreciated.
Muu - should be ok on the Honda side of things but ta for replying.
Just wanted to add thanks for posting this up. It was very useful recently along with another previous post on here
