On these injector boots . I keep reading gray and black and Black are at the 
rear . My 73 SB always had black aand brown with the brown ones at the rear 

 In 2009 I checked from the ECU plug to the injectors to make sure the 
proper plugs were on the proper injectors and at the same time while working 
on it a bit later I replaced the fuel lines so I removed the NOS injectors I 
got in 97 to cut off the short hose to  injector crimp and I'm pretty sure I 
put them back where they belong at least both brown are at the rear , what's 
left of a black on is one #1 and no boot on #3 .

 Were boot colors always the same since mine is a NOV 12 73 built date car .

 For arguments sake if I had swapped 1 & 2 and 3 & 4 injector plugs the 
engine wouldn't run very well since the injectors fire in pairs timed to the 
trigger points and cam shaft./ valve opening 1 4 3 2 so 1 & 4 fire then 3 & 
2 .  The cables to the injectors seem to have a set in them and seems to 
only way to know for sure is to check from the ECU plug .
