It has taken a bit longer that expected to get this TBI swap done.
After going 4 wheeling to a hard t rail here in Colorado I was motivated again to get this TBI swap done. The blazer would die and be hard to start and would not run on its side. This was a huge hassel and made the trails harder.
So needless to say I am going to get this swap done.
Ordered the VSS and the 4 wire O2 sensor. I will pick up a KS and I should have everything.
I decided to use the stock intake and just drill/machine out the 4 center holes. This solves the issue of coil mouint and sensor mounts.
I will have a question when I wire the O2 sensor when I get it. I have the relays but do not know what color O2 wires go to what parts of the relay? I bought the AC delco AFS75 O2 sensor and the relays are off a 83 ish caddy.
I am hoping to start wrenching on it next weekwend.
Thanks again for all your help and all the great information in this thread.
