easy .... hardest part is making the whole in the firewall(if installing the pcm under dask) and getting all the connectors threw it by yourself! ..... then again my truck was made for 1 wire ignition ..... my firewall grommets were probably a bit smaller then most of your guys .....

mine had a 6 wire hook up ..... i used 10 gauge for everything

1 - Ground
1 - Ignition (attached to 3 fuses)
1 - Main Batt. (1 more Fuse)
1 - Fuel Pump Power
1 - Tach Wire
1 - Speedo Wire


everything else just plugs right in ..... the o2's connector that came with my harness are the 2x2 style o2 sensor. the 02 sensors that i bought for the 01 truck were a 4 pin flat connector, i just took them back and got the 02's with a 2x2 pin connector, ls1 or vette style then parts guy told me.

easy to hard

you might want to replace the relays that come with the harness. I have gone back to the clutch fan, the 17 hp was not worth the headache IMHO.

There have been a few people that have had issues with the relays, i think if you upgrade them the harness will be fine.
