The larger of the 2 red lights is on permanently although the van stills starts and drives, it has started cutting out a bit when coming to a stop.

Any help much appreciated.

If it helps anyone, using the OBD I worked out that the ecu was not receiving any speed signal. Fixed the cable for the speedo correctly and no light and no stalling
