e36 speed sensor to ecu

i have BMW e36 the speed sensor in the diff is connected to the dash , which i want to connect to g4+ link xetreme. the question is how can i know which wire to connect and to which wire in the ecu thanks

There is For the E36 an Electronic Trouble shooting manual. http://www.jonkensy.com/DTA/ETM/1996%20BMW%20318is-c%20-%20320i%20-%20325i-c%20-%20328i-c%20%20Electrical%20Troubleshooting%20Manual.pdf

Does this help?

what i have found is from cluster x17 wire 2 that's the speed sensor output which from i searched it goes to cruise control and read 48 pulses.

so can the link g4+ deal with that kind of connection ?
