Wiring solved . Now my next querie ,is there a flow or circulation diagram somewere showing how to convert to FWC and particurlarly showing FWC of the Manifolds as well . I have a 1996 new in crate 5.7 liter Volvo GL but it doesnt have FWC package. The kit costs over $1000CDN. I figure I can use my old Heat exchanger and put on the old thermostat housing. The other question is can you drill and tap the risers and manifolds to put in hose fittings to FWC the manifolds as it seems Volvo made no accomodation for FWC the manifolds. I have mixed reports on this
