I have added schematic diagrams for the Ignition, the Fuel pump and the immobiliser to my site:

Only recognised TVR owners will be able to view the immobiliser circuit

Dave,

I noticed the relay marked "Fuel pump" in position 8 on Steve Heaths diagram and assumed that it was there rather than hanging down as on the later cars. Is it an extra relay? I have no way of checking as my car is 1996 and both it and the ECU relay were on the Xmas tree until I moved them to the bulkhead.

Dave,

I wonder if the extra relay could be to buffer the immobiliser relay, some early cars seem to have 3 circuits protected.

I still have an early Meta immobiliser (But a later alarm module) that appears to have three protection circuits but only two the starter solonoid and the ignition are used.
