Thanks for the replies, would it be a vacum to the diaphram or boost?i have two hoses left I'm unsure off. One that would have came from the original cross over pipe also the one from the solonoid switch on the firewall. Thanks for the help appreciated.

It's a small valve behind the booster on the firewall, has two wires to it and a vac line in and out.ive just done the egt removal, inter cooler and taken the inlet off and gave it a clean out, but I removed it all then went back to work for a month so forgot where they went

Hi, I've searched everywhere and unable to find out some info on some hoses.there's a solonoid near the brake booster and a line coming out could you tell me where it goes? It's vacume unsure if it goes to the top of the injector pump or elsewhere. Is a td27t 90 mod terrano.
