Calling older F3 Dallara Opel Spiess car owners!

Hi guys

I am looking for any info such as a pin out drawing of the Motronic MS 2.2.1 ecu that was fitted to early Dallara Opel Spiess F3 cars. 92-94ish

Im also trying to discover what lambda sensor was used on it, what exhaust gas temp probe.

Hope someone can help

cheers
