Iirc there late 90's
I went from EWS 3 to EWS 2, from what i remember EWS2 has the receiver separate to the module, EWS3 has the reciever built in.

Wiring it up i cant help but id say it can be done.

Depending on part number, the ECU can be recoded to use EWS 2 or have the EWS function deleted.

ok. but i cant get my head round where the ews module would be plugged in, would it be onto the original e30 loom under the dash somwhere or on the e36 engine loom somwhere? and would i need the plug from a e39 loom in order to fit it? sory about all the questions, its just theres nothing to be geeked online like there is for ews 2

I dont know anybody thats retrofitted EWS3, with the M52 ECU being able to have the EWS deleted or re-coded to EWS2 there is no point.
