Wiring test

Now maybe you have seen , am rebuilding a gte , now I bought it stripped am now at the point where testing the electrics , got that I think is the loom live , so got this on to the batt , no engine fitted as of yet , so no dash lights can't seem to get the likes of wiper motor to work or the indicators either . The hazzards work tho and the heater blower . Where should I be looking or am I missing something, cheers mac

Maybe an earth? Mine has one near the passenger headlight to the chassis

Yeah that on new metal . Would the engine need to be in first for this to work .
