I'm installing a autopage 610 starter, it's having probs starting, it cranks it but it fails to start,so rather than do a voltage check for starting i'll hook it up to the tach, but were exactly is the coil located in these trucks?

TACHOMETER|white             |   |ECM *3     

*3 ECM is located near the battery, down low, between the fender and the fan under the black plastic cover. On the 4.3L, the tach wire is at pin 20 in the connector labeled 'red', and VSS wire is at pin 3 in the connector labeled 'black'. On the 4.8L, 5.3L, and 6.0L, the tach wire is located at pin 10 in the 'red' connector, and VSS wire is located in pin 50 of the 'red' connector.

Is up to the installer to test all wires with a DMM whenever possible.
