you just need the thick red/black which goes to starter pin 50, or if terminals are unmarked jump both spades with live from the battery whichever gets the car cranking is where the red/black goes. if it wont crank on either spade then check starter & battery, plus battery cabling
for the ignition this is fed by the black wire on the ignition switch pin 15, the red wire should be permanent live. on the ce1 fusebox you have 1 red wire from battery to one of the large fusebox P spades, and red wire to the ignition switch from the other.

Low voltage at the red/black wire means ignition switch, and or the interlock relay on a Automatic.
The automatic shifter interlock thing is at the rear of the Bentley.
Also depending on if your new loom was out of an air bag car, there is the bypass you have to do if you don't have an airbag.

Current flows from Ground to the Power source Basic electrics.
The starter gets ground from the case bolts.
The starter has 12V on the big red wire of the solenoid full time as it is connected to the battery directly.
When you turn the key switch from run to start, a couple of things happen.
1. The load reduction relay is disabled and cuts the power to the head lights defroster, blower motor and hi-draw items.
2. At the same time you have 12V being applied from pin 30 of the ignition switch red wire, through the switch and out on pin 50 red/black to power the starter solenoid, as well as the ignition circuits.
So verify that you have 12V on pin 30, of the ignition switch and pin 50 when you have the key turned to start.
If you have 12V on pin 50, with the key in the start position then you have an open between the ignition switch and the starter.

If you measure from the ground to the "30" run on the fuse panel do you have 12V.
There are differences in the layout of the Digi vs the CIS and then Motorola alternators (plug in) to the Bosch ( post)
Some that I have seen over the years run the main power to the starter solenoid from the battery to the starter and then from the starter to the alternator.
The Digis that I have had all had separate wires from the Battery to the starter and from the battery to the alternator… Where as my 81 Golf Diesel did the cascade from the battery to the starter and the starter to the alternator….
The Bosch Alternator had 2 wires the big honking red that goes to the main post, and the itty-bitty exciter wire (blue) that goes back to the alternator warning lamp circuit in the dash.
So my questions is do you have 12V + going in to the fuse panel from the battery?
Here is some good information on the front and rear of the fuse panels.

See the link
Central Electric 1
P is where all the power to various things go and what not, as the ignition switch is connected to it as well as other things…So you should have a red power wire from the battery to P…..

you should have a thick red to battery live terminal which plugs to one of the 2 large fusebox P spades, then you have a thick red from ignition switch to the other big P spade.
then theres a thick brown to the battery which is your main earth, it runs to a 4 way white spade plug behind fusebox. theres a spade wire out the back of the block which goes to the claw above the fusebox. then in the front of the white block you should have 1 spade wire from dash loom, one from white engine loom D plug and one from the fuel pump.
as a rule of thumb if you have a brown earth wire inside a brown or black spade housing, this goes to the white 4 way earth spade block. if its in a clear housing or bare then it goes to the claw above the fusebox

this pin will be empty if rear loom wasnt from a GTI. few options, change rear loom, add pin to e/14, or use spade N with inline fuse.
more details in my fusebox FAQ link above

either use a 67/80/167 relay and wire the digifant red/yellow to d/13, or you could use a kjet fuel relay which is triggere from the rev counter feed. Id recommend you use the digifant trigger though

The digifant has a rev limiter on it as well, but to be honest in all the years that I have had digifant with 2 dailey drivers I have never had to replace a fuel pump relay.
