Help With RD28T

[unlimitedpower]

Hi,

Im doing an engine conversion into a car using the RD28T from a early 1994 Nissan Patrol.

I need a little bit of info on a couple items on the injector pump.

1: What is the white vacuum type pot thing with the metal arm coming off it below throttle bracket (has vac line off it)
2: On the return line on the pump there is a red wire coming off a coil type thing, Does this need an earth or 12+ feed (what does it do)
3: Does anyone have a wiring diagram they could scan for me, Showing TPS and pick up for engine speed,

Thanks
Brett

Might be best if you put some pics up mate. as for the wiring diagram, we have the manual here in pdf you can download. Which will have everything you need. Or get a Gregory's car manual. I have both and they are really worth having.
