hey,  
im working on getting my rb25 running but i ran into a problem with the wiring, i had the upper wiring harness wiring converted and have that all installed but now im trying to figure out how to connect my fuse box and i cant find the plugs on the rb lower harness that hook up the fuse box.

i was told that s13’s use the stock KA lower harness and convert a couple plugs but according to my [drifting.com](http://drifting.com) dvd they used the rb lower harness. also when i sent out my wiring they didnt want the lower harness so that means it doesnt need to be converted. can someone clear this up??

thanks!

The fuse box for the Rb25 from the R33 is in the trunk. Does that help or am I high already?  
Maybe the connector you need is there.
