c4 swap no 4lo?

[noracin]

Ok guys i just finished up switching out the overdrive trans to a c4 on a 94 ranger 4.0 this weekend everthing works fine accept 4lo.I did wire around the neutral safty switch to start it because there is no plug in for the truck to go to the tranny.I assume that the 4x4 module needs to know that the tranny is in park or neutral to shift to 4lo does anybody know where to look at wiring for this or how to wire around it? thanks Larry
