New Life for a truck passed its prime

[flattopwill]

I have a 60e harness. My friend Tim repinned the main connector for 4l80e configuration. He said that I only needed one speed sensor? The trans is definitely acting retarded and inconsistent.

Allen, you say you WOULD drive it?? Im not sure it would drive if I wanted to. Tim said that it wouldnt drive right. He said somethin about not having downshift and TC lockup. ??


Oh and I forgot, we got the speedo, tach, cooling fan and SES light hooked up. After taking out the gauge cluster it was still very hard to access the wires for the gauges. For the speedo we just spliced in the old VSS wires (1 purple w/white and 1 green w/black intertwined) with the new VSS wires. For the tach, we just sent the rpm signal from the new ecm to the coil signal wire from my aftermarket Sunpro tach. Ive read that aftermarket tachs have to be set to 4 cylinder mode to correctly recieve the rpm signal from the new ecm but I didnt change anything on my tach and it works fine. For my cooling fan we hooked it up so that I can turn on a switch to turn it on or leave the switch off and let the ecm turn it on at the correct coolant temp. For the SES light we just ran the wire from the new ecm to the SES light wire from the old harness. Since it was hard to get to the wires behind the cluster we just found the right wire (using an ecm connector diagram) on the old ecm connector, cut it off and connected the new SES wire. BTW, the SES wire is pin A10 brown on the A connector for the old ecm. Still have to configure cruise control.
