Help! Whats this warning light? RJES wiring loom

[grizgut]

I gave a 2.5 subie engine conversion using an RJES loom and this large red light on the dash has come on and stayed on. Van still seems to run ok although it has started cutting out sometimes when coming to a halt/slowing down.

Does anyone know what it is please?

MIL, aka Check Engine lamp, at a guess..

Thanks SyncroAndy, it is the check engine light. Worked out how to get the failure codes from the ecu today. Looks like ecu is not getting the vehicle speed signal, should be relatively easy fix.
