-A wiring instruction on how you add fuel injection control to what would formerly be a carb'd X19.
This section covers the interface to the Fuel Injection harness only. This would be your
starting point. If you have all the hardware from a Fuel-Injected X that you want to
put into your carburated X1/9, this is what you'll need to do it.
To complete this section, you will need:
1. Fuel injection "dual relay" plug. (Midwest Bayless?) It would be nice to get the
plug with wire lengths already attached for ease of connection.
2. Assorted wire lengths of:
10 Ft. 12Ga Red
10 Ft. 14Ga Brown w/white stripe
6 Ft. 14Ga Green w/black stripe
10 Ft. 14Ga Pink w/black stripe
10 Ft. 16ga Red w/black stripe
3. Electric Fuel Pump. (The Bosch pump is recommended)
4. Two ATO fuses with in-line holders (sockets) 7.5Amp and 10 Amp
Use solder (recommended) or crimp connections as desired.
To finish the job, you'll need to obtain the rest of the Fuel Injection hardware.
This section covers the interface to the Fuel Injection harness only.
Refer to the photo referencing placement of the wires into the connector and their destination points.
It is OK to add these wires to your existing setup and fuse accordingly using separate ATO-style fuses.
The dual relay and Bosch ECM takes care of fuel pump management.
No need for anything special attached to your oil pressure switch or other to make the fuel pump work.
The Fuel Injection Harness (not shown!) plugs into the left of the relay and draws it's power through the dual relay.
This modification handles ALL control to the fuel pump, injectors, MAF sensor and other sensors
once connected to the FI harness. Basically, it's all about this single white plug shown below.
Wiring instruction:
Details are not covered here, but you'll need the rest of FI pieces and mechanical parts to complete
the system. Part of that list includes:
Fuel lines installed that accommodate the FI system
Fuel Injection Harness
Bosch ECM
Air-Fuel Meter module
An Injector rail and associated FI hardware (plenum, air intake hoses, etc)
Four Injectors
Cold Start Injector
Throttle position sensor
Knock Sensor
Crankcase Fume emissions Valve (the name escapes me)
Hope this is of use to those who want to convert their old system to Fuel Injection. -Bob
