M52 swap EWS issues

[Ahmedsinc 414]

Has anyone here successfully swapped an M52 into an E36? Have installed a B28 loom, DME & EWS into the project B30 E36 (94 325i) but while it cranks it won't start. Have plugged INPA in and it comes back with fault 18 - EWS signal. As the loom & DME are being used in a pre EWS car I have only connected the bare basics on the EWS module: 

1 --N/C
2 --N/C
3 --N/C
4 green to DME (through X20 pin7)
5 red/ yellow to switched 12V 
6 --N/C
7 brown to ground
12 --N/C
13 --N/C
12 -- N/C
14 -- N/C

 

I have the transmitter sharing switched +12v with the EWS, some guides say to supply the unit with constant +12v? Also, as the transmitter unit came without plugs I initially had the signal & power wires backward but this has now been fixed. 

 

Failing an obvious solution, is anyone here able to delete EWS from an MS41 DME?
