well thats good to hear.  I am done pulling the harness except the two connectors on the left side of the transmission wont come out.  I tried everything to get them off but i am afraid of breaking them is there some trick to this?  Its the two that go to the little black box thing next to the gear select lever.  It looks like it might be some neutral sensor or something.

They can be a pain! That's the trans range switch. Soak them repeatedly with penetrating oil. I can't tell you how many I've had to finally just break to get them to seperate. Patience is all I can say or you'll be replacing the switch.

around $130 with a discount.  They are a pain to remove without breaking.

wow guess i will keep tinkering with it then. 

Started looking into the harness and i cant decide whether i want to go standalone or try and use the fuseblock to power the whole truck.  would be a good upgrade from the glass fuses and all ofthe relays are on the fuse block.....i will have to do some more reading.

Well i got the harness all stripped down and I think laying the way i want it.  Not sure about some connectors though.  Anyone know of a connector glossary with pictures of the connectors and wire colors?  I found one a while back but i cant remember where.  Any help would be great i have looked for hours and cant find anything.

I'm not sure, but I thought Vile had access to info like that or posted something like that before.  You may want to PM him to ask if he does or if he could point you in the right direction.

Ok so i got to put more time in on my harness today and cleaned up most of the routing and didnt really get to delete much as i am going to be running smog.  (There is a lot of smog crap in this harness!!!)  I think i pretty much have everything routed how i want it so i can start making wires longer and shorter now.  Does anyone know what these two connectors go to? 



Any one know if i need to run the secondary air pump to be Cali legal?  Seems a little redundant if you ask me.

Got a chance to get a little of clean up done today.  Used some dollar store oven cleaner on everything and now it looks good.  Pulled the intake to investigate some oil in the throttle body and cleaned that all up.  I like the intake gaskets on this motor o ring type gaskets and clips on to the intake manifold.  very nice.  Truck should be here at the end of next week so then i can start pulling the old motor and setting this one in there.

Had to go away to work for a while.  Got back and my truck was in the driveway!!  The wife had it delivered for me for my birthday while i was gone.  Took a few pictures and started tearing it down.  I took off the front end so nothing gets banged up during the swap.  Saw how dirty it was and had to start cleaning and painting.  Took some pix along the way.  I plan to pull the motor over the holiday and start cleaning up the engine bay then drop the new motor in.  Heres some pix:




There is actually a mouse living in a little nest next to the carberator....see if you can see it!! lol

I see a Livermore license plate frame on your truck, are you near that area?

Beastie_3:  I grew up in Livermore but left when i went in to the military.  Havent been back in about 10 years now but i want to get back up there soon.

Well got off work early so i put some time in on the truck.  Got the motor out and started cleaning all of the mouse terds from everywhere.  I am hoping to get all of the wiring cleaned up and hidden.  Anyone know what i can do with the A/C and heater wires to reroute or clean them up? 



Note the rats nest on the intake manifold!!

So i have a 87 blazer tank and sending unit for the fuel system for this thing but i ran into a snag.  I was looking at the fuel tank pressure sensor and i dont know if it will fit in the top of the sending unit.  Can this thing go in the top of the tank?  It looks like the sensor just needs a hole to work so i was thinking maybe a hole in the tank could work if i cant squeeze it into the top of the sending unit.
