Alright, got everything done and in the car except the fact I need a powersteering pulley and extend one of my o2's. The only problem is that for the dash wiring there are 3 connectors coming through the firewall like the LT1 and 2 are the same but one of the other connectors are different, not sure what they go to and how I need to wire them up. Getting pics tonight and also the same deal with under the hood wiring, 2 connectors connect to the harnesses but one is left alone, a grey one with nothing to go to, probably goes to the underhood fuses and will have to be wired into my dash to work on my fuse boxes. Will get pics as well. After everything was installed, hoped to atleast get it to start and turn over but did nothing, no radio, just lights and the noise when you got the door open. No fuel pump noise either. If anyone could provide me with help Id really appreciate it, and the people who have done it in an LT1 car. I could solve this by buying the LS1 dash and wiring but wanna see my options first and if its feasable. Engine is a 98 ss motor with wiring harness and PCM, 6 spd.

Thanks

 

dont know where these grounds should bolt too




the white connector, from the LS1 harness





the black connector in the LT1 dash harness





the 3rd body harness connector, have no idea where it goes





as it sits

 

Those grounds bolt to the back of the head. Should be a stud sticking out back there or just use a bolt.

Sorry,cant help on the connectors.

 

go to www.ls1tech.com to the hybrid section. They have all the wiring schematics for your problem in the FAQ sticky.

What did you do for the fuel issue? Run 97 vette rails or go with another fuel line and a FPR?

 

97 fuel rails with the walbro LT1 fuel pump.

 

I always think that looks weird, the old style radiator support and LT1 intake elbow, on LS1 swaps.

 

From what i've researched... theres not much other way to do it unless you do the LS1 front end swap.

 

theres a way but it calls for a flat, custom radiator support, and cut it so air can get sucked through the airdam, and then it will fit under the LT1 hood, otherwise conversion.
