I'm in the process of putting an efi engine together for a project car. Since it's an older vehicle with no efi this implements having to also install the computer and harness. I don't have the computer or harness. What I do have is the engine and the intake, engine harness, injectors, sensors, thorttle body, and hoses. I'm wondering how I can tell if the intake is a HO mass air unit. The cover is missing so thats no help. Are their any areas where the speed density and mass air systems are different to which I can check. Thanks in advance.

They are the same

How about to find out find out if the engine harness is a ho or regular one? So I know what type of firing order to wire it.

I can get casting numbers on each part, intake, egr, tps, ect. If that would help anyone inform about this intake. One last thing the harness has a connection for something right next to where the egr connects to is this something for speed density systems? As you all can see I'm really clue less when it comes to efi so I need all the help I can get. Thanks guys.

There is no difference between the mass air intake and the speed density intake. The only thing that makes the two intakes different is the vacuum tree that mounts on the underside. The Speed density unit has a provision to connect vacuum to the MAP sensor mounted on the firewall directly behind the intake. The difference in the wiring harnesses are few, but subtle. The Mass air harness has an extra connector to plug into the mass air meter and also has different pin locations for the Thermactor(smog) pump. If the harness you have is Speed Density, it can be upgraded to Mass Air. I upgraded my car to Mass-air this summer. Here is a great article that can detail the conversion from speed density to Mass-air, so it may help.

As for the connector near the EGR, that may be the TPS connector

Well I found out a way on how to convert it to an HO harness. Thanks guys. I still don't know what that plug in is for. Well actually two of them I know one of them has to be for the oxygen sensors. I'm just not sure wether it's the one with with the 3 contacts or two. I guess I'll find out when ever I get the oxygen sensor harness. I will most defenitly convert to mass air if it's not. Just need to find a good used stock mass air that and a stock HO intake top. Anyone know if the saleen one is better?Thanks again
