4L60e PNP/NSS wiring questions - The 1947 - Present Chevrolet & GMC Truck Message Board Network

First off, swapping an 01 LM7 and 4L60e into a 69 c10.

When I go to wire the PNP / Neutral Safety Switch, the smaller 4 pin (c1) connector all goes back to the ECM, simple enough.

The larger 7 pin (c2) connector is where I am in doubt.

All but the ground wire (pin D) go back to the under hood fuse block, which I don't have the other half of and will be making my own to replace.

I dug around on LT1Swap for a while and came across some wiring diagrams.

Does this look correct?

A - Not Used
B - Ignore
C - 12v Key ON
D - Ground
E - 12v Key START
F - To 15A fuse, then Rev Lights
G - To relay for starter
