Default DIY wideband and autometer gauge? uberdata ECU questions

ive been comming around here for the last...2 or 3 months regularly and about the last year or 2 off and on and i must say i have learned a lot! i finaly decided to make a name because i want to turbo my car (B18A1 CRX with 93 teg grey plug harness(dont ask) and wwaayy too much work) ive done tons of searching on the web and most places lead back to here in some way or another. i figure since this is THE DIY car site on the net, i might as well start with a DIY question! ive been reading up on the DIY wideband and it seems the only way to keep tabs on the a/f ratio is with a volt meter or building ANOTHER board for a display. is there way to wire it in to an autometer gauge? i would like to perminately mount mine somewhere in my car and be able to keep tabs on it full time if possible.

once all this is up and running i plan to put uberdata in my ecu. the only problem is now im rocking a 93 B18A1 automatic teg ecu (not sure of the code) and im not too happy with it and dont want to chip that one. unless yall think it would be worth it? i was told i need a PR4 but if im not mistaken this is out of an OBD-0 car, no? i didnt think obd-0 and obd-1 had the same plugs?

thanks in advance for any info that can be provided im really looking forward to getting this thing running

i dont know the wires that leave the gauge. is there just a positive and negative that you wire to the O2 to get "readings" off the stock O2? from the best of my understandings for the DIY WB you have a positive and a negative that leaves the "controler" and you hook youre DVM to it and read voltage comming out of it and match the voltage readings to a chart off of www.diy-wb.com
