I bought an Omega mars 22 remote start/keyless entry for the blazer. I have a wiring sheet specificly for my blazer telling me what wires I need to connect to for my 04 blazer but I'm looking for the actual diagrams for the blazer to see where the bcm,pcm and the lock wires etc.... run so I can actually find them. Can anyone let me know where I can find the wiring scematics for and 04 blazer?

 

A wiring diagram will not tell you where the wires run...

 

True, Acording to the paperwork I need the bcm, pcm and ignition harness. There are alot of others but they are a wire here and there. I will be having help with this project but, I would like to be able to map it all out before I start.

NOTE *4 IMPORTANT !!!!! this wire MUST BE CONNECTED as IGNITION #2 for REMOTE STARTING!!!!!!



You will need a bypass for the Passlock II system, I suggest the PLJX or GBMP. Google either of them. Fairly cheap as well.

 

Much appriciated, thank you. Any idea where I can find the shematics for this stuff also, bcm, ignition, pcm. Like you would find in the back of the service manual.

 

I just had 1 installed in my 2000 Blazer, is it worth the trouble to try to deal with all trouble you run into and save a few bucks? It cost me 210.00 out the door installed by people who do it all day long with a lifetime time warantee. IfI have trouble I can just bring it back. Said and done. Good luck to ya.

 

Other than the back of a service manual, you could get an AllDataDIY.com account. They will have all of that stuff.

 

Well, the problem I'm having is that noone wants to install it for me because I didn't buy it from them. I have yet to ask anyone I talked to if they would install it for me on the side. I'm still trying to decide if I want to tackle this or sell it on ebay and just go buy one and have it installed by them or what. Decisions, decisions. I would really like to do it my self just for the sake of doing it, I like to learn and work on stuff but, on the other hand I really dont know what I'm getting myself into.

 

I hear that, Well, if you could get to an employee of one these shops, and ask them if they want a side job, maybe you can get it done that way, or do like you say sell it on Ebay, and have it done by a shop. I would try first, at this point, and see if you could get to an employee, pertend you want to ask them a question or something ! Cash deal ! You'll get someone ! Good luck.
