Td5 fault codes

In middle of td5 conversion and got following code ls on nanocom.
Currently running on garage floor, no air con fitted and alt belt off as pas pipes not connected.

Running msb ecu, 10p engine

With nanocom i get the following faults.
1) tachometer drive open load (current)
2) gearbox/abs drive open load (logged)
3) glowplug lamp drive open load (logged)
Glow plug relay has power and signal from ecu and plugs are getting power ( not tested plugs)
4) air flow meter low (current) ( suspect bad maf)
When i goto rev engine up it picks up from idle 770 to about 950 and then coughs and returns to idle and engine warning light comes on.
The get driver demand code.
Have tried changing setting from 2way on pedal to 3 way, come completely out of diagnostics and turn ign off. Wait a short time and restart and still the same.
Running an immobiliser removed ecu
Starting to pull hair out now. Have got another throttle pedal being delivered hopefully tomorrow.
Any help greatly appreciated

do have 12v at the MAF plug

pin 3 =12v + pin 1= 0v pin 2 = sig out to ecu

looking at the plug with clip at the top left hand pin is (1) only power up with ecu

Have tried changing setting from 2way on pedal to 3 way, come completely out of diagnostics and turn ign off. Wait a short time and restart and still the same.

how is going work as you missing extra wring in your loom for the 3 way pedal set up 3 track throttle pot used from 1A605426 defender

1) tachometer drive open load (current) this is ecu output drive for tachometer fitted or not
2) gearbox/abs drive open load (logged) do you have ABS or auto gear box ? or did ECU parts set up have one or both

3) glow plug lamp drive open load (logged) this is ecu output drive for glow plug lamp on the dash

Ita a manual, no abs and no rev counter.
Currently running it up on garage floor before fitment so the glow plug light is not connected so that explains that one
