ok im going to do a 92 infinity g20 radio. and first i can find any information about the harneses or anything about this car. i was guessing to use the 92 nissan sentra kits b/c i think its the same car.
second i for some reason went to crutchfield to see if thaey had any info and when i typed in what car it came up that i needed some special adapter Scosche FAI-1A-Nissan1 for adding aftermarket radio to the existing speakers. i think its bull cause i just put an alpine cva1003 in a 2000 g20 with out anything besides the wireing harness. so please let me know what you think and if i also need the antena adapter i think i do.
sorry for all the questions
thanks
Here you go: first, there is no required kit for these vehicles it is called an iso mount, meaning you will need to use the factory brackets from the old radio.
second, you are correct on the harness, but you also need a Nissan Diversity antenna adaptor.
hope that this helps!!
