Mk2 Gtd clocks into mk1 loom

ive got some mk2 gtd clocks to go with my gtd engine, when i got the clocks i also got the loom off of the clocks to the mk2 fuse box.

Would it be possible to splice the mk2 loom into the mk1 diesel wiring, then add an extra wire for the alternator readings??

Also does anyone have any diagrams which state the different purposes of the wires so they can be matched to the mk1 wiring.

Hope this makes sense.

Cheers
