is the Focus mk1 fuse box computer (pcb) driven?

[magpies]

I'm going to rewire my TVR S1 (1988) and looking to use an under bonnet fuse/relay box - there are a number on ebay at a reasonable price. I've looked at more modern boxes but they have internal pcb and need to talk to the cars computer which make them no good. Does the mk1 Focus have this or is it a 'normal' old unit?
