84 740 no OBD1...?

I bought a 84 740 running, was going through the engine and seen that it didnt have a cold start valve or an OBD1...is that common n can I install one from a 89? would I have to switch computers..? I also notice that theres a valve at under the trottle body that regulates the idle...never seen one of those before...I had a 91 740 I wrecked last year n an 89 I just bought for parts...anyhow thank u for your input if u can help out....
