On the loom supplied with the SM4 there are one relay to control the injectors and the fuelpump. On a sierra cossie with standard fuelpump, is this sufficient? or will i fry the relay/blow the 30A fuse?
User manual says that the SM4 draws max 16A, less depending on injector type.

 

Drop Mark Shead or Mad Rod a pm they will help you

 

Not sure on the std pump, but the 044 locks out at 18 amps, so really needs another relay, as it's very close, easy just do a pump rewire/relay at rear and helps your car as well!!
