i have a 99 blazer LT and i need the wiring harness to upgrade to a better cd/dvd player.
now i've searched the forum and found several posts which say i need a (m) 70-1858 or a (s) gm02b or dash kit (m)993300 or (s)gm1588,
i've googled these numbers and the members are spot on with what they say.
my problem is that none of these are the same as on my truck, so my question is are the european blazers different to the american ones and if so where would i buy one.
thanks guys.

Hi, I ended up cutting the connector off the Blazer and soldered a standard connector block on to the wires, you can buy the standard ones with just the wire tails ready to connect. Left an inch or so of cable ends on the old block, just in case it ever has to go back, also watch the dash adaptor kit, I had three before I got the right one.
Found the details The radio adapter I have is the autoleads ref FP-27-02 that is the one fitted to my Blazer I got it from In Car Music, 605 High Road, Leyton, London E10 6RF but they are listed on the web. It takes standard size head units and has a small slot/pocket underneath.

thats brilliant thanks for all the help.
