Yeh I read your post, but thats a early Kjet to Kjet swap, the electronic changes between early 90s MB and mid to late 90s are vast and far reaching. The swap from 103 to 104 24V is a easy 2 day changeover because the cars are from the same era with easy parts interchange ability.The 320 104 swap is fairly heavy going with a donor car but the 202 104 electonics are can bus and require many more protocols.
