There are a few unique aspects to the right hand drive set-ups compared with their original left hand drive counterparts. So, such simple items as fitting a bulb in the check engine light position doesn't actually work in some cases as possibly no such thing exists on RHD, while left hand drive has it. (Thinking V8 diagnostics, for an example)

But the check light still requires a trigger, doesn't it? Which is the two contacts in te lid of the relay.

Btw. If someone identifies the correct relay, I'll edit my previous post accordingly.
